Traffic crosswalk signal question (MP or GQ?)

Not sure if this should go in GQ or MPSIMS, as I don’t know if it is factual or not, plus it’s a little silly.

I recall having heard, that somewhere there’s a place where the crosswalk signs, instead of displaying the typical default:

“Don’t Walk” / Walk" message

actually displays -

"Don’t Walk" / “Run” :eek:

Is this true or just some joke or UL nonsense?
