Where is the most embarrassing place your tummy has rumbled loudly?

during an exam , the whole room is silent and u just hear a LOUD rumble, and im like.. does this have be happening now, reallly, and then i cant concentrate on the questions because im hoping it doesnt happen again, then i try to hold it in. like that works, which it doesn't of course xD, and then i look at the clock, as if staring at it i could move the clock hands with my mind, thinking if i do have some mind control/time shifting power now would be a good time to find out
