Awards do not always have to be serious to be meaningful. Adding the funny element to them makes award ceremonies more interesting. Everything from popular sayings to making up your own award titles can be used. Think of other funny award shows, like the Razzies, when you are coming up with your funny names.
For a funny spin on awards, have an original award name, like "Most Valuable," and put a funny spin on it by writing a qualification underneath. Something like "Most Valuable...in the Kitchen" can be given to the person who cooks the most in the kitchen. Another example is "Most Improved...at using the Copy Machine."
Famous Lines Awards
Give awards that are based on funny lines from movies. For example, take a famous like, "Go ahead, make my day" and give it to the most cheerful person in the office. You can write on the award that it is given to the person who is positive and makes your day. Decide on the awards you want to give out ahead of time as this will make it easier to find the best lines to go with it. Another example for a person who rarely misses a day is the "I'll Be Back" award.
Making up your own awards is another funny idea. Much like the Razzies, awards given to bad actors, make up categories and give out your own awards. For example, the person who always tries to get out of work, give him the "Slacker of the Year" award. Or for someone who is always sick, give her the "Doctor's Best Friend" award. These awards poke fun at people so do it in a tasteful way that is not offensive to the person. You can also give funny positive awards like "Fastest Typer" to the person who types the fastest in the office or "Boss's Dream Employee" to the person who is the hardest worker.
Change the shape of the certificate so that it not the standard square certificate. Try to make the shape relevant to each award, or use a shape to enhance a specific award. For example, if someone is known for working out a lot, give him the "Gym Rat" award and have it in the shape of a dumbbell.
