DUDE, My shit blocks the toilet all the time, thats why the plunger in my bathroom is one of the best purchases, i cant believe how small the hole in the bowl in the apt complex is. I dont know how anyone shits without blocking it. I get pretty happy when I flush and it doesnt block, it makes me feel happy, lol lol.
Seriously man, I shit bricks, and block it all the time, kinda embarassing, so i flush and run when i use public ones, hahahaha. It might have to do with the fact I am 6ft7 and weigh 285 lbs, but i still dont get it.
