kymou ....when is PACO going to jump on your back as you climb those stairs 
(I saw the video just now lol)
Telling the truth, I couldnt do it for two reason.
1. I was really really weak at that momento and even i couldnt do that joke.
2.Last week i injured a bit my glutes during a heavy set of squat and i felt still strange about my glutes when Paco jumped on my back.
Then I droped him naturaly.
