A police officer is hammering furiously on a guy’s door. When the guy opens the door the officer says; “Do you know what GBH is?”
The guy say; “eh, no I don’t.”
The officers says; “Do you know what GTA is?”
The guy is just as clueless and says no.
The officers pushes on unperturbed; “Well, do you know what AS is then?”
The guy shakes his head and says; “ No officer, I don’t know what AS is. Why are you asking me all these questions? Am I under arrest?”
Whereupon the officer replies; “No. these are just initial inquiries.”
