I think %60 of us on this blog can use this excuse:
Excuse #6: You're a cougar, and your group of red-hatted, Samantha-from-Sex-in-the-City-worshipping gal-pals are interested in checking out the new Hollywood meat, i.e. sexy vamp 22-year-old Robert Pattinson. WARNING: If you are a dude, this excuse does not work for you. Gathering a group of brohams to go scope out 18-year-old Kristen Stewart - whom you've had a crush on since Zathura - is very, very creepy. Yes, we know that's a double-standard, but we're just trying to keep you off the sex offender list. Please be careful.
HERE is the rest of the list.
