Amen to the cell phones.

If someone's going out with me on a date, don't bring it.
If you bring it, turn it off.
If it has to be on, don't answer it.
If you answer it, you'd better be a vascular surgeon on call.
If you TALK to the phone instead of your date, you'd better really like the person on the other end of the line, cause I'm already gone.
