Call control

There are always PA announcements in TTC stations along the lines of "299 Ossington, call control; 299 Ossington, call control." I hope that the resulting phone call goes like this:

"Hallo, Control, this is 299 Ossington."
"Hallo, 299 Ossington! I was expecting to speak with Tony Murchison."
"Ah, well, you see, Control, as a matter of fact, I am Tony Murchison."
"Hallo, Tony! I thought you just said you were 299 Ossington."
"I did, Control! I thought it might be a good idea if I used a code name."
"Ah, so that if any enemy agents were listening, they wouldn't be able to identify you, you mean?"
"You've got it exactly, Control."
"Very good work, Tony."
