Roy Firestone has enormous hands.

[@KrazeeClark]

Woah, Nelly! Donz you're on fire as usual. Keith has gone to the "Big House."

[@markjones952]

So Roy Firestone did the impersonation for the first bit? The wording is almost the same!

[@dongiller]

Yeah, that was Roy. He also did the "generic baseball announcer" for the New Dial-It-Services a month later, on May 18, 1982, uploaded here: czcams.com/video/di9_S1QGScQ/video.html

Jackson was great

I remember when Boy George won the Oscar Wilde 250, the 80's were such a great time for sports.
