Going out three times tonight

I know I should probably wait for someone to get around to reading my first post but I do have a dilemna, most unusually I have been asked to go out tonight by three different people. One is for a guys leaving party, another is for a birthday, and one is to just go out and get as drunk as possible.

Now I know what your thinking, you would possibly dismiss the last as frivolous drunkenous. However, they were the first ones to as me to go out, which also gives them right to priority. Hmmm, if only I could combine a few of them then my life would be easier.
