Marshall: You know, I better pee. But when Lily and I get back, we're all leaving.
Lily: Wait, I have to go pee with you?
Marshall: You want me to go to the "bathroom," the most dangerous room in the house by myself? Do you have any idea what could happen?
[fantasy scene of Marshall in the bathroom, accidentally squirting soap in his eye]
Marshall: Ow! My eye! I'm blind! [a bear emerges from the shower] No, no! Not like this!
[back:]
Lily: I don't think we're seeing eye to eye about the likelihood of that happening.
