Even our favorite shows still hold a few secrets, especially when it comes to how the actors got along or actors who nearly made the cut. Laverne & Shirley was one of the funniest shows on television and seemed to always make people feel like things were going to be alright. But, there are probably quite a few tidbits about the show that even major fans never knew.
