After Woo bonds with Lily, Tibor, the alpha male among the forest's raccoons, cuts in. But he tells Woo he's not romantically interested in Lily. After Woo unsuccessfully guesses at several reasons why (including being "sexually exhausted" from other females in the territory), Tibor reveals that Lily is his daughter.
Woo's expression at this revelation is priceless. Not just because he scored the alpha male's daughter, but because of everything he just said to his possible future father-in-law.
