LazyPurple: This guy is trying to start a conga line in 2017 for what is probably the hundredth time.And you know what?[Camera pans to show a dancing Spy] This guy is loving it!
Spy: Magnificent!
His retelling of himself watching Meet the Heavy for the first time. It's the SFM animation for Meet the Heavy, except the camera occasionally shows a Soldier excitedly nodding his head and having a heart attack as Heavy draws attention to his gun.
While explaining how many of the guns in TF2 deal a lot of damage per shot, he brings in The Count Spy.
Count Spy: One shot. Two shots. Ah hah hah! Two shots to murder the Pyro!
"When you shoot these guns, it feels like... like — "BOOOOOOOOM!""
"The second reason why shooting is so fun is because the character models in TF2 are sooooo... THICC..."
The fidgeting Sniper while Serbia Strong plays. The dumb expression plastered to his face sells it.
When describing how movement helps you survive, LazyPurple has a visual demonstration by having an Engineer dodge a grenade. Said grenade flies into the camera, and LazyPurple can just barely say "uh oh" before it detonates in his face.
Later in the video, there's a short animation of a Scout dodging around Sniper fire before beating his head in. The player is represented by a Sniper slapping a keyboard until he gets hit, at which point he begins rapidly spinning in a fit of rage.
