It's hard to imagine, but 'It's Always Sunny in Philadelphia' (Thu., 10PM ET on FX) may have just had its most ridiculous premise yet. The entire episode saw half of the gang hiding out in a complete stranger's house, while Charlie and Mac manned the van outside. Why were they doing this?
Something about Indiana Jones and an art exhibit made them decide that they needed to secure a vase for a museum from a house. Instead, we got to see Frank, Dee and Dennis move around this house while the family came in and out saying cryptic and confusing things.
