Need help with a Cheers (TV show) quote

In an episode of Cheers, Woody says something that’s glaringly obvious. Frasier responds with something like: “Your grasp of the obvious is amazing.” Woody, of course, takes this as a compliment. I’m looking for the exact quote, but to no avail. I wish I could provide more details about the episode, but I’ve poisoned way too many brain cells since then. Any help would be greatly appreciated.

This?

From here

Thanks!
