Oh man, gotta love Bungie's sense of humour. The Man Cannon is a new feature in Halo 3 that will fling objects around multiplayer maps, Morph Ball Cannon-style.

From 1up.com:
In addition to vaulting Spartans across terrain, the Man Cannons will also launch projectiles and some strategically placed boxes. Players can drop grenades onto them, launch the Mongoose (with guys riding Brokeback) off the lift, or even shoot the Warthog (though it's a pretty weak limp off of the lift instead of an airborne exploration).

I humbly request that it make a 'boioioing' noise every time it is activated.
