Some thoughtless wanted Jimmy Fallon to play him a song after we all know the Tonight Show host almost lost his finger in a truly terrifying accident.
The good guy that he is decided to go ahead and make some music, but he needed some help.
Luckily, Chevy Chase also hurt himself in a filthy way (we'll let him tell you what happened) and he stepped in to give The Tonight Show a little soul.
It's just about time for Chase to start making the press rounds for the return of the Griswolds as the awful-looking Vacation reboot? sequel? opens July 29.
As far as the trailer shows, Chase is only in it for cameo purposes, but marketing is marketing.
