Go into a game and press the key that you selected to bind. Now, you have died (or exploded) and acquired the funny. (this guide also works in games that have the same source engine as tf2, like Garrys mod) EDIT: HOLY CRAP OVER 1,000 PEOPLE HAVE VIEWED THIS????

2: Set the launch option "-console" in the properties of TF2 on Steam.

4: Open the game with a QWERTY keyboard layout
