Not really that extreme or necessarily difficult (because I did it without trying very hard), but I'm guessing it's still somewhat unlikely others have done this.
I have been red-carded (ejected) from a high school soccer match as a player, a coach, and a spectator (separate occasions). The last one was done while completely unaffected by foreign substances. The ref gave me a yellow-card for coaching from the sidelines in the wrong spot. I was not the coach nor was I coaching. I was, however, yelling things other than go, kick, yay, etc. which may have been perceived as coach-speak. Apparently, he thought I was coaching again later, so he went all red on me.
