That was a bit redundant Jami. By saying "girlfriends that suck at skiing/snowboarding" you are in essence repeating yourself. This is obvious to any man who knows that all women suck at sports. Therefore any girlfriend would be assumed to suck at skiing/snowboarding and stating this is needlessly descriptive and repetitive.
Your amendment now reads: "You all need to get or bring your girlfriends so that I can come too!"
To pre-empt/prevent any questions or hazings: Yes, Mike you may bring a prostitute as your date and no, no one may bring my sister (note that the two subjects in this sentece are not related, ie my sister is not a prostitute so nice try). That should decently cover all eventualities.
Have a nice day.
Wow that got off topic.
