What starts out as a white lie on Penny's part to avoid an annoying childhood friend (guest star Mary Elizabeth Ellis, "It's Always Sunny in Philadelphia") snowballs out of control as the whole gang is caught up: Jane fakes a pregnancy (complete with fake baby shower), Dave pretends he's terminally ill and Alex fakes a change in sexual orientation. Max and Dave's lonely landlord (guest star Ben Falcone, "Bridesmaids"), jealous of their active love lives, looks for ways to evict them, until he takes a shine to Alex. - 2011 ABC Studios
