Taking the original stranger to the next level and particularly applicable to Marvel fans.
You
will need a piece of red cloth or cloak to symbolise the cloak of levitation.
Lean on your arm until completely numb as you normally would when attempting a stranger.
Once numb, fully wrap your
hand in the "cloak of levitation" and begin the deed.
As in the Dr Strange film, it
will seem the cloak is very helpful in these dangerous situations and
will navigate you and yours to safety.
Upon completion simply discard the offending cloak/cloth and blame the multiverse.
