since "Rintindumb" was found (thanks so much for that) I figured I'd throw this out there, the other shorts that aired in between cartoons, I believe these were from Teletoon, im pretty sure both of these are lost, but just thought I'd see what yall come up with, one was, I believe a cgi animated short about stupid pirates, they would sail the seas with their underwear mast and treated people's "underpants" like treasure, It was called something like "the pirates that steal your underpants", the other short I'm a little more interested to find, it starred two I believe animals of some kid (maybe dogs) but maybe not, who worked as firefighters, and would always fight over women and stuff like that, it really put off a tom and jerry (original black and white 1930s version) sort of vibe a tall guy and a short guy as firefighters who would always bicker and fight about things. these aired in around 2006 along side the Bernard bear shorts.
good to see someone brought this thread back up! but no, sadly it wasn't the hoze houndz i remember that show very vividly, i am not 100% sure about the short with the fire fighter dogs, it may have been one short guy and one tall guy as well, i mostly just remember there was a girl they were trying to impress/save and a fire, its pretty vague but i know it was part of a series of shorts with the two characters who i believe competed with each other a lot
UPDATE: the show about the underwear pirates has been found! Its called "Those Scurvy Rascals" and it aired 26 episodes in 2005. Only one left now is the one with the two characters:0
