I, for one, am guilty of making lots of programming jokes. I did hear, though, that you have a great understanding of programming if you can use it for humor.
So let's hear your best programming jokes!
Note that the best ones are easily understood by many people, so try to stay away from satire, and try to keep it in a relatively popular language that others will understand (i.e. DM, C++, C#, Java, PHP, JS, VB, RegEx, etc.).
