Laverne & Shirley - Season 4 Episode 23

No one believes Laverne saw an industrial spy in the brewery. So she takes it upon herself to prove everyone wrong. She drags Shirley back to the brewery late that evening and they lie in wait for the spy. Both girls after arguing with each other end up soaking wet in a huge vat of beer. When the spy appears the girls confront him. Moments later, the security guard comes in and the girls try to convince the guard about the spy. The spy spins a tale to the guard who is now unconvinced so Laverne pulls of his trousers revealling the stolen microfilm in his sock suspenders.
