Quote from Phoebe in The One with the Routine
Phoebe: Hey, look who I found. Chandler: Oh, hi, guys. Phoebe: You know, birds have a very good sense of direction, so I thought maybe they could help us find the presents. Chandler: Yes, if the presents are hidden south for the winter. Phoebe: Or we could just follow your clever jokes. Any ideas? No? Didn't think so.
