You're not going to bite me. I'm going to take that coffee now.

Come on, now. You don't seem the biting type. Even if you were, you're genetically engineered. That probably gives you some pretty strong inhibitions against harming a human.
And the flaw in my plan is: By stopping to think, I gave you enough time to drink the coffee.
Would you like the cup back?
