how do you hang up nicely?

Just walk into the bathroom, hold the phone up to toilet, and flush. They will say something like, "uhhh are you in the bathroom?" Then you say, "Yeah, I just took a huge $#%@." Hopefully they will be grossed out and hang up. If the person keeps on yapping interrupt them and start talking about how you will never eat taco bell again.
