Exactly what qualifies Frank the Entertainer (no relation to Cedric the Entertainer, apparently) as an "entertainer" is tough to understand.
Basically, he's a man with a mental patient's haircut who takes verbal abuse from his parents. And he lives in their basement.
Beyond that, it's the 15 women competing for his questionable affections who do the entertaining. In this case, that means massaging men who show up for a yard sale.
And that doesn't go down well with Frank's mommy. Let's just say there's no happy ending.
