And now, a confession: We have a soft spot for Colt 45.

It goes way back to high school and some boys we used to hang out with, and it's a story that pretty much stops there, so that now we've revealed too much, let us add that we're relieved we're not the only ones whose 40-ounce memories run deep.

In her college days, Jennifer Keeney held a regular 40-ounce Tuesday night club with a few friends. The club convened after her three-hour "Methods of Psychotherapy" class. "I decided it was so incredibly horrific that we needed to have a 40-ounce night," says Keeney, a Northwest Side resident.

Keeney, now an HR exec, survived that class. But neither she nor we could see this one coming -- a weeklong celebration of the 40-ounce.

All week, the Fifty/50 in Wicker Park is offering 40-ounce specials (and corresponding food specials) to mark what it insists is National 40-Ounce Week. Monday was Colt 45 night. Keeney and her husband were there.

"We thought it was worth a sitter," she says. She posed with a cardboard cutout of Billy Dee Williams, ate a skirt steak sandwich that she says was "spectacular" and, of course, drank a 40-ounce -- or 40-oh, as the kids say.

National 40-Ounce Week at the Fifty/50 ends Sunday. By the way, there's no need to BYO paper bag. The bar has that covered, too.
