Thought of this idea about 5 years ago.
Found out someone had capitalized on my idea about 3 years ago.
Purchased it 2 years ago. Haven't gotten much use out of it, but it's fun when you do.
The fart noises are a little "fake" sounding though. I wish they sounded more realistic.
Also as for the old "obsolete" whoopee cushion. They actually have IMPROVED it (you didn't think that was possible did ya?) and now it is SELF INFLATING. Yes, I mean you use it, and then it has some kinda special cushioning stuff in it that will actually self inflate!! Talk about lazy!
