There are two things I hate getting invites to...weddings and funerals (OK, baby showers, kids' birthday parties, any party involving home/cleaning/tupperware and women's items parties). My reasoning is that usually there's a good man going down.
With that in mind, I may have come up with a great business for someone. Rather than having bachelor parties, have bachelor funerals. Basically it would be the same thing except the theme and what the bachelor gets to do.
