Kasper Hauser is a San Francisco sketch comedy group named for a feral child who was the subject of a 1974 film by MoFi favorite Werner Herzog. They're very funny live, but there's plenty to check out in the first link, such as Spicy Pony Head (mp3) (depicting a difficult interaction between waiter and restaurant patron) and Captain's Log (mp3) (which depicts Capt. Kirk on acid).
