I stuck it in, no problem. Twisted, again no problem. It was the pulling part where all hell broke loose. I'd pull, and the anus would bulge. I'd pull slightly harder, it would bulge a little more. I'd pull gradually harder and harder, very carefully, until the anus ripped wide open but the anal canal was stilll attached. Now all you've done is made it that much messier and harder to get the anal canal out since now it's in two peices instead of one.

This happened all three times I tried it. It might work if you just pulled a little and then cut, but if I've got to use a knife anyway then I might as well do it the old fashioned way and leave the stupid tool home.
