re: The best scene in "It's Always Sunny in Philadelphia"

Did you frick my mom

Pretty much the entire mac and Dennis move to the suburbs episode

Mac bringing his homemade bike into the mediation

Frank being bill ponderosas sponsor and supporting him doing drugs/bath salts at the ponderosa-mcpoyle wedding (they'll make your butthole hot)

Charlie telling everyone that he cut the brakes

There are just a ton of them that kill me. Those are some I hadn't seen listed
