# DSP or signal/image/data processing jokes

Some other StackExchange/StackOverflow sites are entertained with a certain level of humor or fun. What is your favorite “data analysis” cartoon? is particularly worth mentioning (IMHO) this xkcd cartoon on causality and correlation (DSP folks know what I mean):

So Is humor allowed in answers? I hope so, se for instance:

Humor in signal processing or image processing does exist, albeit shallow, and narrow-spread. I have encountered it first (I had zero humor before) at the ICASSP 2000 DSP humor exhibition in Istanbul, Turkey. The image below comes from Humor in DSP by EURASIP:

So I believe that we deserve some humor and joke tags and actual lightness. Go ahead!

• I very much like the topic, I am wondering however if this thread is more appropriate in Meta (?). Similar to the dsp-puzzle tag, it would be nice to have a dsp-humour (?) tag. It will be challenging to formulate it as a question though ("Why are you dragging this chain?", "Have you tried pushing it?") – A_A Jan 23 '17 at 9:37
• This is an appropriate comment. I will go on digging how it is handled on other SE sites. One suggestion: turn the joke into a genuine post on the underlying DSP theory, and move it to a community wiki? – Laurent Duval Jan 23 '17 at 9:49

An airplane is leaving Warsaw (the capital of Poland), and gets caught in a terrible winter storm. The plane rolls, pitches and yaws. The crew is expecting the plane to crash or break up at any time. But one DSP student suddenly stands up and asks some passengers on the right aisle to move across the plane. Passengers are reluctant but the student insists. “Hurry, our fate depends on your move.” Most passengers quickly leap to the other side, and suddenly the plane stops shaking. The pilot, who had a DSP degree too, enjoys calming everybody:

"Thank you for the Poles who have moved to the left-half of the plane for stability."

Another visual pun (dedicated to @MarcusMuller) is this chocolet decomposition:

• Duplicate? Delete one or the other. :-) – Peter K. Jan 22 '17 at 16:42
• Double pole clicked at the origin I guess :) – Laurent Duval Jan 22 '17 at 16:49
• Love that chocolate decomposition! – Marcus Müller Jun 10 '17 at 20:17
• I had two cakes, one primal and one dual – Laurent Duval Jun 10 '17 at 20:30

More of a terrible visual pun:

The FFTiramisu.

• I cannot accept it for ethical purposes, but let Cookey and Turkey algorithmics gods bless you – Laurent Duval Jan 22 '17 at 19:06
• It was, indeed, blessed with deliciousness :) – Marcus Müller Jan 22 '17 at 19:08
• I have added a terrible culinary pun similar to yours – Laurent Duval Feb 12 '17 at 17:31
• @LaurentDuval awesome! Sadly, I can't double-upvote – Marcus Müller Feb 13 '17 at 14:28
• I had two cakes with a different chocolate flavor, and obtained a dual-tree chocolet transform. Unfortunately, parts of my belly became redundant – Laurent Duval Feb 13 '17 at 15:36

I personally also consider this very early XKCD to be a signal processing joke:

• The "Meouw" part is TOO "time-based" to get credit for:) – Laurent Duval Jan 22 '17 at 19:20
• Upvote the cat joke! The meouw-law compels you! (especially since the dynamic range for giving or not giving credit is pretty limited) – Marcus Müller Jan 22 '17 at 19:26
• Upvoted is already done. Credits are in a different dimension – Laurent Duval Jan 22 '17 at 19:31
• Ohhh! There's a whole class of jokes to be made about distributing fish! – Marcus Müller Jan 22 '17 at 19:41
• And in the category of bilingual jokes, there's a lot of (rather lewd) potential in leakage translating to the same German word as licking. – Marcus Müller Jan 22 '17 at 19:42

Crazy Audio Fx ilustration lol

more:

• Most 1D signals concepts illustrated in 2D. Nice – Laurent Duval Jan 23 '17 at 15:32

In high school math class I finally got the courage up to ask the cute and brainy girl at the front row out on a date. She just looked at me with a discouraging face and as she waved her hand face down horizontally from side to side. I asked her "What's that mean?", and she said "It's the Fourier Transform of this!" as she raised up her middle finger to me. After joining DSP.SE, I finally figured out what she was talking about.

• It misspells 1337N355! ;-) My VW Beetle has the license place F34TUR3. :-) – Peter K. Jan 22 '17 at 16:42

Ever wondered why there's "Live Aloha" bumper stickers? Aloha is a remarkably unhealthy approach to vehicular traffic.

I was going to tell a joke about the appendages of an absolutely normal cat, but it has a really fat tail.

• I was going to retweet your joke, but I now prefer to signal it – Laurent Duval Jul 26 at 15:12
