Quote from Barney in The Pineapple Incident
Barney: Hello. Ted: Why are you sleeping in our tub? Barney: The porcelain keeps the suit from wrinkling. Lily: Wait, were you here when I went to the bathroom in the middle of the night? Barney: Don't worry, I slept through it. [laughs] I totally didn't sleep through it. Oh, and wow! For a little girl, you've got a big tank.
