Quote from Dave Kim in Adam Graduates!
Adam: Where the hell's my mom? Dave Kim: The only possible answer is she's trapped at the bottom of a wishing well. Brea: Dave Kim! Dave Kim: It's more plausible than her missing her schmoopie's special day. Brea: Adam, I'm sure she's just parking. Or maybe Dave Kim's bottom-of-the-well thing. It is odd.
