BUT

Ted: The but is there's always gonna be a but. No matter how great things are going sooner or later it's gonna get ruined.

Robin: Ted, everyone has baggage you just gotta look past it.

Ted: You see, everyone's got some baggage. It's part of life but like anything else it's easier when someone gives you a hand with it. - HIMYM

This is probably one of my favorite episodes in the series since I first watched it a few months back. I love how emotional baggage was objectified as actual baggages.
