I saw this on YouTube by sunstripe31 and felt a strange urge to put it here. So here it is!
GET A JOB
Brian: (singing) I'm not wearing underwear today! No I'm not wearing underwear today! Not that you probably care much about my underwear! Still, nonetheless I gotta say! That I'm not wearing underwear today!
Eve: GET A JOB!
Brian: (depressed) Thank you...honey.
EDIT: Thanks to AngelXScourge for telling me some stuff about this song. First, the names of the cats. The guy cat that sings is named Brian, and the girl cat who tells him to get a job is his fiance, Christmas Eve (I shortened it to Eve in the thingy...). The song is by Avenue Q and it's called "I'm Not Wearing Any Underwear." Thanks, AngelXScourge! Hope this makes it better...
