Sonny & Cher "I Got You Babe"

Harold Ramis asked Chicago radio legend Steve Dahl to play the role of the radio disc jockey in Groundhog Day, but he passed. Instead voiceover artist Richard Henzel played the iconic role. As far as casting goes, Ramis also considered Tom Hanks and Steve Martin for the role that ultimately went to his friend Bill Murray. Unfortunately, Ramis and Murray's friendship took a dump after filming the movie. At the time, Murray was going through a divorce and seemed to bring that pain onto the set each day by being hostile and habitually late. Things got so bad, the pair didn't speak for nearly 20 years after the film wrapped. Murray finally buried the hatchet when Ramis was on his deathbed in 2014.

Commodores "Oh No"

Jokes that definitely wouldn't work today: in a scene from the 1983 movie National Lampoon's Vacation, Clark Griswold gets lost driving his family from Chicago to a fictional theme park in California called Walley World. He somehow ends up in South St. Louis, Illinois where he seeks directions back to the highway. The Griswolds drive past numerous burnt-out cars and buildings and various stereotypical African-American characters before a basketball-carrying local offers to help (provided Clark pays him $5). The local ultimately gives him directions to another car where "Jack", his cousin, will help him get back to the highway. While this is happening, the hubcaps from the Griswold's Family Truckster get removed. It's then when Clark's son, Rusty, asks: "I wonder if these guys know the Commodores?". Many years later, the movie's director and former-Ghostbuster, Harold Ramis, apologized for the infamous scene. He explained, "The scene was supposed to be about prejudice, when in fact it is prejudiced."
