What's the most "facepalm" moment that's ever happened to you? (Doesn't have to be pokemon related)

Answer here.

I'll share two, the first one was when I was roaming through Black and found a shiny Fearow, sad thing was, I was out of pokeballs. ;~; My other's a bit more complicated, so lemme explain it, I was at my dads workplace and he works at a car dealership, so he had a bunch of cars, one identical to that of his own, so he asked me to fill the car up with gas, me being the retard I am filled up the wrong BMW... Retrds naoadays (: cwatididthar? ;3

My most Facepalm moment was probably when Youtube wasnt working and me and vixy were being very impatient and annnyed by it then finally it started working but vixy didnt notice it in tell a whole hour later when she was going up the steps she yells "OH MY GOSH YOUTUBE IS WORKING!!!" After we were watching it for almost a hour XD
