Serious Sam is a first person shooter series developed by Croteam, first released in 2001 and built around huge enemy waves and old school arena combat. Its hero Sam Stone became known for short, cocky one liners delivered between fights, and clips of those lines have circulated for years on gaming soundboards and in edited videos. This I knew it line survives because it sums up the series perfectly, a lone hero completely unsurprised by yet another ambush, and works just as well outside the game as a reaction.
