Can’t lie, BL2 has the best quotes out of all three games.
My top two are from the douchey bar patron from the Tiny Tina DLC.
“Hey baby – I’m hung like a Vault monster.”
“Ow! Oh c’mon! Alright, I’m sorry! I’ll never say nothin’ douchey again, I promise… B*TCH!”
First time I heard the second quote I was crying of laughter.
