Big Bang Theory, “The Malice Destruction”

Leonard needs to go on a road trip out to the country to pick up some supplies for his secret new business, but is afraid to go alone, so he enlists the help of Raj, Sheldon, and Howard. With the gaggle of nerds piled into the RV, they head out to the country. Sheldon refuses to use a truck stop bathroom, causing Leonard to pull over at a farm house to see if they could rest up there. The farmer agrees under one condition: that nobody touches his three sexy daughters.
