I was doing a show one night and decided to do a trick i have done a MILLION times without any problem.
I would place my right foot on a higher surface that the stage, at this bar it was a drink stand, then proceed to slide my left foot out and into a split. The result is pretty cool in that my legs are past 180 degrees in the split, you can only imagine how this looks.
WELL this particular night i was dancing to "Gansta Love" by Eve featuring Alica Keys. Went into the split and my left knee, which i disslocated when i was 18, popped out on one beat of the song, and then popped right back in on the next beat, almost like it was choreographed that way.
As if that wasn't enough pain, the song was less then half over. I had ton continue dancing. NOW many of you are probably like forget that, but you know... i was raised with that whole show must go on thing.
Mind you there was only about 2min of the song left, but every time i put my left foot down or did ANY of the most basic steps i wanted to slit my throat so the pain would end.
Thankfully it was the last time i had to dance that night and my friend had lined up 4 shots of vodka for when i hobbled off the stage.
