Mooovin' In - S1.E8

Phil becomes annoyed at all the attention Todd is receiving and schemes to bring the attention back to himself when he finds a stray cow. To do so, he pretends to steal the cow, but when he really does lose it, Todd eventually finds it and allows Phil to take the credit. That night, the group discovers that the cow has apparently wandered up the stairs of Carol's house and is now stranded, causing Carol to officially move in with Phil. In a brief flashback, Carol is seen purposely bringing the cow upstairs.
