How I Met Your Mother? That sounds like a generic gang of misfits to me. I'd go with the Paddy's Pub Gang, even though I know they would turn on me and excommunicate me before the episode ends. Hell, I may even end up dead, but it'd be totally worth it.

I'd probably have a better chance of surviving amongst the Workaholics crew. I can at least get high with those guys, but they'd probably scheme against me too.
