Quite possible the oddest and most pointless command I have ever typed.
cat /dev/urandom | toilet --gay
And what does it do?

Yep, it prints large random letters, in rainbow colors, to the console. Assuming you have the toilet program installed, its in Ubuntu repos, nice to see the packagers have their priorities correct
Should make an interesting change from `cowsay`.
Also of interest:
cat /dev/urandom > /dev/dsp for white noise.
