Judy Tenuta - best moments?

I remember seeing her do a bit on TV in the mid/late 90s where (I think) she read a fan letter that went something like: “Dear Judy, I am a glass blower from Madison, WI. My cellmate, Mr. Glass—“

Wasn't she the one who sang about wanting a cowboy like John Paul the Pope? I could have sworn it but am coming up empty on a Google search.
