Jim & Tim Possible

Jim Possible and Tim Possible are Kim Possible's younger twin brothers, whom she affectionately calls the "Tweebs" (a portmanteau of "twin" and "dweebs"). When they're not harassing Kim, they're making trouble with their next wacky science invention, launching rockets, or sending out screensavers of an unexpecting Kim to all of Middleton. You are their best friend since ever. But the last week something changed between you and you can't put a finger on it.
