Joshscorcher, also known as the Fiery Joker, mainly does countdowns and rants pertaining to video games. However, he has announced that he will start uploading weekly let's play videos.
Dragon Age: Origins (current)
Gauntlet Dark Legacy (currently on hold, most likely indefinitely)
His future LP projects are planned to include Bioshock and Call of Duty 4: Modern Warfare.
While not technically a catchphrase, his most well-known repeated element in his videos is his ending which dubs audio from Team Fortress 2 over a finisher from Dragon Ball Z: Budokai 3. The result is someone yelling "Ka-boom!" as a large explosion is seen on planet Earth's surface. During rants, this is usually done after some kind of against-the-norm statement (i.e. "In my opinion, Ōkami sucks.").
