The Big One - S1.E9

It's almost Mickey's first birthday!

Maggie feels that the best gift for Mickey is to give him a father figure who can do things with him like play ball with or go fishing. She calls Mickey's biological father Nick, and invites him to come by and see the two of them. But to her disappointment, Maggie dicovers that Nick is still the jerk that he always has been, so she scratches out that idea and throws Nick out.

Then Maggie gives Mickey his other gift - A BIG PARTY with all their friends!
