I'll bite, with a few difficult to handle objects and possible games.

Bowling balls. They're slick and heavy. The challenge? Place them in elevated bins (they roll into goals via tracks from the bins). But if you place them too hard, a trap door opens and they fall out of the bins. Don't be below them!

(Skips the smaller golf balls and other similar small balls)

Footballs. The odd shape--and the lacing--make handling these a challenge. Throw or punt or kick them into a high goal. Sound easy? Until you realize that there's a muzzle velocity, and a net over the top of the field!


And I'll also throw in the other most-frequently-requested game object, the traffic cone. Slick, heavy, and tough to destroy, and can be tough to tip. Stack them, place them in precise positions (Whaddaya mean you can't see the white X on the floor from 50 feet away?), and don't let the placebo construction worker catch you messing up his line or you're disabled for 3 seconds.
