A while ago someone posted a comic where a shark chick threatened to bite an alien's balls off.
That was hot, one of my favorite things is just the threat of having junk be ruined.
Anyway I found that comic on e6. The dialog is so meh, but here's where she comes up with her genious plan.

Kinda hot, and now you can read the whole goofy comic.
