Mark McGwire finally came clean, admitting he used steroids for over a decade during his playing career, but he disputed the notion that the drugs ever improved his foot-to-mouth coordination.

“I believe I was given this gift,” McGwire said during an interview on Monday. “I took steroids to clobber baseballs. But no pill, injection or cream could ever help someone’s God-given ability to repeatedly cram their own foot in their mouth. I truly believe that.”

Research conflicts with McGwire’s claim since approximately 100% of known and even suspected steroid users have significantly improved their natural ability to jam foot to mouth.

McGwire’s past and current performance falls directly in line with the research.

“Steroids may not improve someone’s natural foot-mouth coordination,” said Scott Borodynko, a Physics professor at Temple University. “But it will certainly give them the power to really mash it in there and the recovery necessary to do it over and over again.”
