Contrary to the suggestions of a particular reviewer, this whistle should not be inserted rectally. The benefit of this product is that it is an oral whistle that makes rectal sounds. The instructions explain this but some people are just too busy to read, it seems. It is for this reason that buying this product "used" is not recommended.
You may wonder what some of the benefits of this product may be. There are many.
1) Sometimes you are too tired to fart.
2) Sometimes you fart but the sound is too low to be heard.
3) Excellent way to clear a seat on a crowded bus or train.
4) Recommended way to sing along to a particular John Cage recording
4'33'' .
5) Perfect, easy to carry equipment for campfire camaraderie.
6) Best way to counteract the effects of Beano
Beano Food Enzyme Dietary Supplement Drops, 75-Serving Bottles (Pack of 3)Product Description
What's funnier than the sound of a fart? Well a lot of things actually, but for those of us that haven't risen above second grade humor it might as well be Shakespeare. I laugh every time I blow into my fart whistle. In fact I have laughed so hard I actually swallowed one. You should hear me talk now.
