Cheers S10E21 - Take Me Out of the Ball Game

Sam ponders a baseball comeback, but when he goes to play a few games he discovers most of the players are much younger and immature than he is. They're acting just like he used to, and Sam doesn't think he enjoys acting like that anymore. Meanwhile, back in Boston, Frasier loses Lilith's favourite lab rat and tries to get an identical one before she returns.
