Hopside Down Beer Glass
Though this is definitely a silly gift, a hopside down beer glass is still a functional kitchen addition for the beer connoisseur. Inside the handblown 12 oz. glass is the shape of an upside-down beer bottle, creating the illusion that the beer will spill at any moment. It's a great companion for a day watching football or relaxing outside.
Homemade Magnets
This is an especially fun gift for a father or older sibling who always imparts his ideas of wisdom. Print or handwrite the guy's most famous sayings like, "When I was your age ..." or "If I were you, I would do X, Y and Z." Then purchase standard magnets at a local craft store, and attach them to the papers. Stick them on the refrigerator as a way to tease the guy with his own words.
Gift Basket
Making your guy a gift basket is a fun way to poke fun at him but still leave him with something that he can use. Pick a theme that embodies his personality, and then fill the basket with appropriate items. For example, if he's a horror movie freak, you can cover the basket with artificial blood and stock it with novelty things like fake eyeballs, skull keychains and plastic severed fingers. To give him something that he can actually enjoy, put his favorite scary movie DVD in there as well.
