I used to play that game! Simpler times! I called it doppelganger, and I would just shout random celebrities names, as if I was seeing the real celebrity, but it was just someone who looks slightly like them. I would have loved to get selfies with these dopples and just pretend I thought they were the real thing to other people, even when they looked almost nothing like them. Until it was so obvious I was taking the piss, there was no fooling anyone any more. Then I would keep doing it just to be annoying! It would never lose flavour.
Cop: "Do you know how fast you were going?"
Doc: "Of course! Eighty-five miles per hour. If you'd let me get to eighty-eight, you would have seen some serious shit!"
the cop fires his gun shooting doc in the chest BANG! BANG!
Cop: "You were threatening me!"
20 minutes later Cop2 arrives
Cop2: "Did you find anything in the deceased perp?"
Cop: "I did! Its crazy! He had this letter on him predicting this entire chain of events. I looks like it was written in 1955!"
Cop2: "Huh, crazy. Well, where did you put his body?"
Cop: "What?! I swear he was right over there! He's gone now! I put two right in his chest! Could he have been wearing body armor?"
And relative to the street you were too fast. There.
I think you've got your unkempt physicists mixed up.
