Oh my! ROFL
I need a tissue! *wipes eyes dry* this is hilarious!
Mine do the silent but deadlies, however ONE day Mozart was sitting there peacefully, and all of sudden we all heard a "PHHHHHHHHHHHHHFFFFFFFFFFFFFFFFTTTTTTTTTTT!" Mozart looked just like that too!, he got up, turned around, and sniffed his bottom, to make sure there was nothing there I guess!
I think he really thought something had come OUT!

My husband and I were rolling on the floor we were laughing so hard at the fact he was so loud and then his reaction to it!
