Mark McGwire doesn't want to speak to his estranged brother Jay because he's writing a book about his and Mark's steroid use together.
Oh no, not this again!
Except, the reason they've been estranged since 2002 is pretty damn funny.
"The brothers haven’t spoken since 2002. They fell out after Jay McGwire’s stepson, Eric, tickled Mark and caused Mark to spill coffee on himself. Mark then swatted Eric on the backside. Jay’s wife, Francine, then refused to attend Mark’s wedding."
Oh, and here's the article about the story, but I already posted the best part. But Whatevs!
BIG MAC ATTACK IS BACK, CUT SOME SLACK JACK!
