is this actually a condom, or just the bottle lid?

I suggest you go buy a condom, a bottle, compare the two and post your results. This way we will know for sure.

Have a hot girl pose with it in her mouth, too. You know, to eliminate all the variables.

I think Bansho meant something like this: http://img257.imageshack.us/img257/2738/bottlerz7.png

Yeah, I'm pretty sure thats what it actually is, of course, I'm also sure it was meant to look like a condom.

a fine example of a visual double entendre, exhibited in form of an ambiguous object.

always here to resolve things huh LaC ;)
