Programming jokes

I've been saving up a few random programming jokes. Since I no longer care about post lengths, I shall post them now! Warning: they are all horrible, vile puns.

1. “... and, since the language was essentially a combination of Perl and Haskell, we of course decided to call it Blaise.”

2. The following four (?) lines of code are potentially legal (if probably useless) C++, even in the absence of preprocessor defines. (Writing a prologue to actually make it compilable and executable is left as an exercise for the reader.)

o.o ^_^x <_< n_n >_> z_z ;_; ~_~ -_- *_*
‍ ‍ ‍ <(o_o)>~~~ o_O; x.x <3 +_+ 9.9 >_<!!!
‍ ‍ ‍ (T.T )( T.T) ._. H_H ^o^ '_' %_% x_X;

3. Loosely related to the above: one of the things I love about working with computer graphics is the fact that I'm working specifically with 3D graphics. This means I get far too many opportunities to write the following:

for (size_t i = 0; i<3u; i++) { ... }

4. “So this guy walks into a pipe...”
