Party On, Steve

Just watched Wayne's World.

Noticed that it included a that's what she said joke:

Garth: I'm getting tired of holding it.
Wayne: That's what she said.

Wondering if that's the original that's what she said joke.

And wondering, if it is, if Steve Carell and The Office* give Wayne and Garth the credit they deserve.

*Note: That's a link to a blog post I made a few months ago involving John Lennon, Dr. Jekyll, and Ricky Gervais.  It would have been a link to one of my favorite scenes from the The (American) Office, but NBC doesn't want me to do that.
