Looking for a clip from a Steve Martin movie...

[largo1]

I figured someone here might know which movie its from. I don't really remember anything about the movie itself (what can I say..., it was the eighties!!), but in this scene Steve Martin is doing a crazy, ridiculous, over-the-top dance. I'm thinking the scene took place outside, maybe on some kind of patio or terrace. Might have been "My Blue Heaven", but I'm just not sure.
Anyone recall this scene??? Anyone? Anyone? (yet another great eighties movie!)
Thanks,
Suzanne
