I believe it was this very episode that spurred our colleague Shane Sebastian to a life of surfing and being a caped crusader... caped campus crusader that is.BTW, does the Joker say "Cowabunga, Cowabunga"? I thought that was the Ninga Turtles & Bart Simpson's line.
Yeah, cowabunga started on the Howdy Doody Show and was adopted by the surfing community in the 60s/70s. TMNTs started in the 80s. So, I guess the answer is, yup, the Joker says Cowabunga, but only when he's surfing.http://www.urbandictionary.com/define.php?term=cowabunga
