Quote from Marshall in Matchmaker
Marshall: Robin, open the window! [After Robin opens the window, Marshall throws the cockamouse out] Robin: It can fly. Lily & Marshall: Wow. Marshall: Be free, mutant beast. I'll miss this private war of ours. I grew to admire your tenacious. Oh my God, it's headed this way. [Marshall slams the window shut. The animal flies directly into the glass]
