Society Mugs(1946)

Overview:

Muriel Allen needs an escort to Alice Preston's dinner party, and her maid Petunia mistakenly places a telephone call to Acme Exterminators instead of Acme Escorts. It's Shemp and Tom to the rescue, and they're assumed to be cultured college seniors. Guest of honor Lord Wafflebottom follows the pest exterminators' lead in proper American party manners, turning the dinner party into an uncouth display. When mice are conveniently spotted, the boys go to work, disrupting the party and the entire mansion.
