Can't find this great bit I remember

[valenzetti 1]

Fellow CBB/CDRR fans, I need your help.

I remember listening in one of the early episodes (1-70) to this great freestyle song that a character did. I think the performer was one of the regulars, like (but probably not) Paul F. Tompkins, but I just can't remember exactly what the bit was and when was it.

Does any super-fan know what I'm talking about?

Not the Halloween episode (77)? That's the only freestyling that I remember.
Other than that, Jerry Minor with "Poppin' Bottles" (18)?

Do you remember any lines?

If you can give me any specifics I'm sure I'll know it, it's just too vague right now.
