If I were to try and utilize a guilt trip I might ask that if I ever helped you out of the goodness of my heart at some point that you make a small donation.  Have I ever done any of the following for you?

• Driven you home when you have been drunk
• Backed you up in a bar fight
• Helped you dispose of evidence
• Located the clown "exotic dancer" for your party
• Taken care of you when you have been sick
• Bandaged you up, iced you down or helped with any other injuries
• Helped you with your outfit, hair or make up for a special occassion
• Invited you to be a guest in my home
• Taken the blame for your gas attack so the person you were flirting with didn't know it was you
• Decorated for your party
• Protected you at Halloween Haunt
• Cooked for you
• Made you a cocktail
• Bought you a drink while out
• Introduced you to people you love
• Introduced you to people you had sex with
• Made you a birthday cake
• Watched your kids even if they are now adults
• Said prayers for you
• Organized a trip you've enjoyed
• Recommended a bar in Vegas you enjoyed
• Covered your butt at work

But I don't want to resort to guilt trips, and yes most of those were jokes.  Just donate a dollar or two if you know anyone who has suffered from breast cancer.  Or help me spread the word.

Thanks for your help.
