Earlier this year, the worlds of Abbott Elementary and It's Always Sunny in Philadelphia collided in the first half of a Philly-set crossover. The first half took place at the ABC home of Abbott, meaning the Paddy's Pub gang had their usual R-rated antics toned down. However, with the second half taking place on FX's Always Sunny, get ready to see a whole new side of Abbott's teachers. Abbott Elementary creator and star Quinta Brunson discussed the other side of the crossover in a recent appearance on Jimmy Kimmel Live.
