I remember in San Andreas and Vice City they cops said some real funny stuff. My favourite quote in Vice City in fact was the cops saying "Make me run and I'll get all sweaty." They also said stuff like "I'll BEAT you for this," "Don't make me run." And another one; "I'll chase you but I've had too many doughnuts..."
"C'mon, hit me, I wanna retire!"
In San Andreas you had the funny guys in the chopper. "Hey, she's cute..." "She, is a HE. That's a guy!" or again, something on those lines. GTA IV had so many voice clips but the cops were still funny.
In GTA V the cops are way too serious. Just telling you to "GET THE f*ck DOWN" and "STOP RUNNING" and this kind of boring bullsh*t. What happened?
