Ubuntu has a history of semi-weird codenames for their releases (Warty Warthog, Hoary Hedgehog, Breezy Badger, Dapper Drake). The people in #ubuntu-offtopic on IRC regularly make parodies on these names. Their brainfarts are collected at http://wiki.kaarsemaker.net/UbuntuNames.
There are some really funny ones, like Horrible Hippopotamus, Nutritious Nightingale, or Spastic Swan.
Feel free to add more on that list if you know some more Ubuntu-like names.
