Ahhh, frustrating, I've been trying to find a gifset of that scene, and haven't found one - from Four to Tango. BUT, this tumblr has gifsets of a lot of things from all the seasons, and I found a few moments from the list in the season 3 tag, which is super helpful!
And I'm sure it has more in the other season tags as well
