Welcome back to the thread, Tgame.
"Tim the Enchanter" - As a medic on arena_grid_walls, assist in exploding the entire enemy team.
"The KILLER RABBIT!" - As a scout with the Sam Hat (optional), launch yourself into a group of enemies and decimate them all with the Crit-a-cola and baseball bat/Sandman.
"Holy Hand Grenade" - While kritzkrieg charged, explode the killer rabbit after he attacks your team.
"The Legendary Black Beast of AAAAARGGHH!" - Be a demoman in a dark place with stickies. Use them well.
You know... cuz he's... black... geez... I feel bad now...
Also... I'm surprised nobody went "HERP DERP
WII SUX BAD GRAFICKS" at the Wii pic. I'm gonna use it to start up all my Steam games from now on.
Actually, I can only think of two people that would say something like "HERP DERP
WII SUX BAD GRAFICKS" and they haven't posted in this thread.
Now to just get that Wii remote working on TF2....
"One, two... FIVE!" - Get two kills, followed by a triple kill with one shot/explosion/heavy minigun spread (about a second of bullets).
"
How Not To Be Seen" - Spend a good 15 minutes as a spy on meleecheckers where nobody can find you.
