Charlie's life turns upside down when his brother and nephew move in. At the supermarket, Charlie discovers he can use 10-year-old Jake to attract women.

Unsure how to properly discipline Jake, Charlie ignores him after the child 'forgets' to stop feeding the seagulls and leaves the door open, allowing the gaggle of birds to enter the house. Meanwhile, Alan gets a surprise from Judith when he goes to fix her sprinklers.

When Alan's attempt to provide Jake with a fun-filled weekend backfires, Charlie tries to console his brother by taking him to a local bar and getting Alan totally inebriated. As Alan and Charlie travel home, their cab driver offers them some unsolicited therapy.

When Charlie's longtime cleaning lady, Berta, quits her job, Charlie quickly realises he can't function without her and sends Alan to lure her back. Meanwhile, Alan places Charlie in charge of getting Jake ready for Judith, who is coming to take her son out for dinner.

After a drunken night in Las Vegas, Charlie reluctantly attends one of Jake's soccer games and soon discovers the advantages of going to these matches. The players' mothers are quite attractive, and Charlie makes a date with a particularly sexy soccer mom.

Charlie rethinks the way he treats women when he, Alan and Jake are forced to cheer up a pitiful Evelyn after her boyfriend terminates their relationship. Meanwhile, Charlie teaches Jake some valuable lessons about screening calls from women, but the lesson backfires.
