Manitou Springs Great Fruitcake Toss Festival (annually in January)
Colorado is known for it's goofy festivals and the Great Fruitcake Toss is certainly one of the headliners. This Manitou Springs tradition is held every year after the holidays in an effort to dispose of certain unwanted confections you may have acquired.

When:
The 2014 Great Fruitcake Toss festival has been cancelled. Hopefully it will be back in 2015.

Frozen Dead Guy Days in Nederland (Annually in March)
2014's Frozen Dead Guy Days will be celebrated March 7 through March 9. The highlight of the event is really the Polar Plunge, where anyone can sign up to take a dive in a freezing pond. Some people do it for the thrill, some do it to raise money for charities, and some are just plain nuts. There is also a coffin race, hearse parade, music, and many other bizarre activities (frozen turkey bowling???). This is one of the most popular things to do in March for front range residents with cabin fever.
This is probably the wierdest festival I've ever heard of, even wierder than Manitou's fruitcake toss or Leadville's ski Joring. Come and learn about the history of the frozen dead guy and observe some of Nederland's finest citizens enjoying a day in the mountains.
Traffic can become a real problem for the small town so plan accordingly. Parking is available on the side streets but getting to them can take a while.
When:
March 7 - 9, 2014
Where:
The event is held in Nederland, Colorado (at the top of Boulder Canyon west of Boulder).
As more people down in town learn about this festival every year, it has grown from a small event for members of the mountain community to a really crowded winter festival for everyone in the front range. If the crowds don't bother you, come check it out:

Shell Gas Two For One Ski Ticket
For 2014, Shell gas stations are offering 2 for 1 vouchers at several ski areas with a 10 gallon gas fill up. This means that if you buy at least 10 gallons of gas, you get a coupon good for a free lift ticket if you purchase one full price adult lift ticket. The deal is good at several ski areas.
Unfortunately, full price adult lift tickets have become so expensive that this isn't much of a "deal". But if you just want to ski one day at a participating resort this year, this will get you on the slopes for less than full price.
In Colorado, 2014's participating resorts are:
Copper Mountain
Crested Butte
Loveland
Monarch
Powderhorn
The SkiFreeDeals.com web site has a full list of participating Shell stations and ski resorts.
