Pranks a Lot - S3.E21

The kids play prank after prank on one another with impunity...but when one of Holly's (a fake eviction note) backfires and almost gets Ben kicked out of the country, Holly may have to become a bride to keep her British beau from being deported to the land of tea, crumpets, and Benny Hill! Meanwhile, worried that she's too stodgy, boring, and neurotic, Val buys a Porsche...then goes nuts trying to keep her wild impulsive "investment" pristine.
