Ah, friendship -- it weathers any storm, helps heal broken hearts, and provides television with some of its most hilarious and touching moments. Friendship is equated with consistency, and helps provide an anchor for viewers. No matter what changes may come, friends are forever (most of the time). From 'Perfect Strangers' to 'Scrubs,' and everything in between, we take a look back at some of your favorite best friends from TV and see what they're up to now.

Now: Though LeBlanc's 'Friends' spin-off 'Joey' was a flop, he's found success on television again with the series 'Episodes,' in which he plays a fictionalized version of himself. LeBlanc also sometimes produces, and was the executive producer on 'Jonah Hex.' Perry hasn't had much luck in post-'Friends' sitcoms -- both 'Mr. Sunshine' and 'Go On' were cancelled. He's also appeared on episodes of 'Hollywood Game Night' and 'The Good Wife.'

Strong declined to reprise the role of Shawn for the series, but continues to act, as well as direct, write, and produce -- mostly short films.
