Quote from Barney in Desperation Day
Lily: Marshall, tomorrow's Valentine's. Don't you want to be at home on our couch, cuddling up under a warm blanket, watching the Predator use his heat vision to stalk helpless prey? [meanwhile, at MacLaren's, Barney is on the look out for women using his heat vision. He spots a lone woman:] Barney: [makes Predator clicking noise]
