V-Day - S4.E14

A tuxedo-clad John is on his way to his ex-wife's wedding in Connecticut when he stops in a bar because, in all honesty, he doesn't want to attend the event. Instead, the grumpy doc would prefer to have a few drinks, bend the ear of Frank the bartender for a while and get home in time to see the Knicks game on TV. And in the end, that's what he does, but not until he recalls (via flashbacks) his miserable Valentine's Day to Frank. While John complains about being all alone, the wise barkeep helps him realize how truly lucky he is.
