Costume Parades

The Friday night costume party is one of the unique events that sets Chicago Area Mensa’s RG apart from all the others. Mensan grown-ups take dressing up to a new level. Costumes range from fanciful to funny to elaborate and elegant, but the thing for which Mensans are best known are the pun and word-play costumes. In all of them, Mensa-style creativity is obvious. Bring your sense of humor, and your wits, because our puns will keep you guessing and giggling all night long. Make sure to consider this year's theme, ripe for pun-filled humor! Puns, however, are not a requirement. View our pictures to see costumes from ’WeeMs past.

The kids costume parade will precede the adult costumes as in past years to encourage more adults to attend and support our youth. The keynote speaker will be featured on Saturday rather than Friday between the kids and adults costume parade. but for those of you who have younger children who might be overwhelmed by hundreds of strangers, who have children with early bed-times, or who simply want to avoid having to explain some of the (occasionally suggestive) puns, this will give kids a chance to dress up and compete for prizes at their own party. Then get yourself into costume and come to the main event.


Everyone on the dance floor! Requests taken.


Pretentious Drinking

Liqueurs. The fancy stuff. Polished, cosmopolitan, perhaps even a bit snooty. The stuff you graduate to from beer and wine. You’d like to know more but, gosh, look at that price. What if that pricey potion isn’t quite the palate pleaser you expected? Rejoice! As in years past, you can sample some truly amazing liqueurs, and your money’s no good here! We will supply a wide range of weird and wonderful concoctions from around the world. You can determine which you’d like to own, which should be left on the shelf, and which you should give to your arch-nemesis as a thoughtful gift. Obviously, you must be of legal drinking age to join us and show proof at registration. Snobbish accents and extended pinkies optional.

Photo Booth

The return of the Photo Booth—this year it will be located near Pretentious Drinking—where you can pose with friends wearing all sorts of fun and silly props. You’ll be given a copy of your photos as a keepsake. See some of the prior years’ photos (2019 , 2018 , 2017 , 2015 or 2014) to get an idea of what to expect.

Werewolf of WeeM Tournament

For those under 21, in addition to the daily Social Deduction games, we will offer a special Werewolf tournament just for teens and tweens.


We’ve also had requests to bring back the Cookie Contest as well as the Scarecrow Decorating Contest from previous years. If you’re a local member or attendee interested in hosting or helping with either of those or another contest idea, please let us know by contacting our WeeM Chair  or signing up to add it to the program list..


More dancing and often karaoke!


Chicago Area Mensa Board Meeting

CAM members are invited to attend. Submit any GOBS requests no later than Friday to give the GOBS liaison time to process it during this busy weekend.

Awards & Announcement

Find out who won the volunteer raffle — volunteers winning smaller cash amounts must be present. Hear about the AG and other RGs. Congratulate several deserving members who have been volunteering in our organization upon whom AML service awards will be conferred. And the Hell's M's announce our RG’s party animal.

Amazing Race: WeeM Style Tournament

Join us for the “Amazing Race” for Mensans! Based upon the popular TV reality show, teams of 2-4 competitors complete a variety of tasks, some cerebral, some lighthearted, on their way to the final “Pit Stop” and victors’ bragging rights. Our version is designed for all ages and activity levels, and is sure to be one of the most memorable things you’ll do this weekend!
