It's a reference to the old Doom games where you'd get a pickup message for every weapon you could find.



"You got the Pistol!"

"You got the Shotgun!"

"A chainsaw! Find some meat!"

"You got the Super Shotgun!"

"You got the Chaingun!"

"You got the Rocket Launcher!"

"You got the Plasmagun!"

"You got the BFG9000! Hell Yes!"
