Conor McGregor shows off his pitching form at Wrigley Field

Flashback: 50 Cent throws infamous wild pitch (0:39)

On May 27, 2014, rapper Curtis "50 Cent" Jackson threw out one of the worst ceremonial first pitches ever. (0:39)

Ceremonial first pitches have a history of going shockingly well or surprisingly bad.

MMA star Conor McGregor's first pitch during Tuesday's Chicago Cubs game against the Minnesota Twins at Wrigley Field was no exception to that rule.

The Notorious MMA's time on the mound could have gone better -- to put it mildly.

McGregor stepped on the pitching rubber and appeared to be ready to deliver a solid pitch, but the ball sailed wide right and missed its intended target. By a lot.

His pitch drew comparisons to other less-than-stellar tosses.

If there is any consolation for the former UFC featherweight champion, McGregor can be at peace knowing other big-name celebrities have struggled on an MLB mound too.
