The Big Deal - S3.E18

Lester's construction company has the chance to be purchased by a multi-national company. The lawyer that is over the proposed merger sub leases the apt and next door, and he and Mary start off on the wrong foot from the beginning. He requests tickets to see the Pointer Sisters, makes Mary cook a steak, (after she'd already made fish) mistakes her for the maid and tells her to clean his apt for $3.00 and hour.

When Mary can't get tickets, she, Rose and Sandra dress up as the Pointer Sisters and host a party for Thurmond. Lester decides that he does not want to sell.
