Mark McGwire joined the long list of celebrities lampooned by South Park. It happened in South Park episode 113 entitled "Up the Down Steroid."
McGwire: What a perfect way to end the home stand, by hitting sixty-two for the city of St. Louis and all the fans. I truly wanted to do it here and I did. Thank you St. Louis.
McGwire: Only sixteen players have hit fifty or more homers in a season. To me, that's a very special milestone.
McGwire: I study pitchers. I visualize pitches. That gives me a better chance every time I step into the box. That doesn't mean I'm going to get a hit every game, but that's one of the reasons I've come a long way as a hitter.
McGwire: I don't know if I want to break my own record. I think I would rather leave it as it is.
(After finishing the baseball season with a two-homer day, giving him a record 70 for the year. Sept. 27, 1998)
Mark: I mean, it's unheard of for somebody to hit 70 home runs, so I'm like in awe of myself right now.
