From my buddies over at Manvite, here's a new feature I'm going to have for you every month: Your Guy Event Calendar.

We'll let you know about all the important stuff going on that you may want to get the guys over for... or build a party around. (Any excuse, right?)

Then you can head over to Manvite, make up an e-invitation (without all the frilly borders and pictures of kittens you get on other invite sites), and mail it out. Boom. Instant party.

This month there's plenty to celebrate:

You've got the Kentucky Derby on the 2nd... break out the whiskey...

Then there's Cinco de Mayo on the 5th... or as we're calling it at my place, Tequila Tuesday.

Megan Fox has a birthday on the 16th, and I will definitely be celebrating the day she was born...

And don't forget Memorial Day, the official start to summer, beer, bikinis, and barbecue.

I'll be expecting your invites.
