In in interview with Mark Callaway, he says this before his debut at the 1990 Survivor Series "I was terrified [Vince McMahon] was going to call me and want me to be a big egg, to shave my head and eyebrows and be 'egg man.'"
Even though he references the Gobbledy Gooker, I had just finished a long bout with 'Sonic Adventure 2' and imagined Mark Callaway as Dr. Eggman, a bald, wildy moustached robotics expert contantly feuding with a blue hedgehog coming to ringside not on a motorcycle, but in his Eggwalker.
That's like printing money, I say.
I've said it before and I'll say it again: Sean O'Haire ate Brendan Fraser. Celine Dion? More like Cell-Out Dion!!
Also, as I understand it, they've been running a more "active" drug scan since they got caught up in the negative publicity of the SI steroid scandal, and Mercury might have gotten caught on strike two at a time when he couldn't aford to.
