"The 100th episode is a huge milestone many TV shows never get to see because a program is often canceled due to low ratings, the cast cannot return, the show has nowhere to go, or forces that are out of anyone's control shut down production altogether. There are a number of shows that have crossed the golden bridge and managed to entertain us well past the 100th episode, but when it comes to the number of sitcoms that have achieved that feat, that list is significantly shorter.
Imagine having to come up with new and funny storylines that feel fresh and incorporate unique jokes time and time again. That is the challenge sitcom writers face.
Only the best of the best have managed to hold their own for so long, and when they did reach that 100th episode, everyone made sure the breakthrough was memorable. Here are 15 of the most iconic 100th episodes in sitcom history."
