one was in Dallas at a private lesson with Shaolin. I was a little fat at the time and we were working open guard passes and chokes form rear mount. we worked on techniques for 30 minutes and rolled for 20. At the end he let me know several things to work on. he said
"you know a lot of techniques but your belly is in the way of them. you need to lose the belly to get the techniques to work better."
he basically punkd me over my belly
I was bouncing at a club one night and there was a group of people there that could not hear. they were hanging out, drinking, dancing, they could feel the beat of the music and they would dance to it.
as the night progressed one of them got a little tipsy and got in a little fight, none of the bouncers could control him so i went in and grabbed him. the dude dove for my feet and for some reason I pulled guard, i wrapped him very tight and and started scooting out the door with him, i got him outside and as i let him go i kept him close to me and patted him on the back, I guess he understood at that point it was time to stop and he calmed down.
we were rolling one night and a black belt was rolling with an upper level blue. the black belt had N/S and was bearing his pelvis in the face of the blue belt and setting up an arm bar. The blue belt all of a sudden said "i feel something squishy on my face", the entire class stopped and laughed at him for a long time. a good example for one of those "motivational" posters.
