Tip # (whatever number you want it to be)
If you're on a date, and you realize things aren't working out between the both of you, first asked to be excuse to go to the bathroom. Make sure you have your cellphone with you before you to go the bathroom.
When you finally reach the bathroom, turn the alarm clock on your cellphone and set the alarm sound to your current ringtone! That's right, RINGTONE!. Make sure you set the alarm time for 5-7 minutes before your current time.
Walk out of the bathroom and meet up with your date again. When the alarm goes off on your cellphone, make it look like your answering the phone. Then look very surprised, giving the impression that something horrible happened. Then tell your date, "I'm sorry, but I really need to get going." If your date asks, "Why, what happened?". Tell your date that it's very important and I can't discuss it right now.
Then you can make a clean get-a-way!
