There are two Saint Otises of Prague.
The first Otis is the Patron Saint of Elevators Going Up.
The other Otis is the Patron Saint of Elevators Going Down.
They were martyred when their elevators collided.
How elevators in separate shafts collide was a total mystery, and the priest who was called to deliver last rites to the two Otises declared it a miracle.
The Vatican handled the rest.
And this is why you see OTIS on every elevator.
Well, the ones that the Saint Otises watch over.
There’s no Otis on this one?
Um, I’ll take the stairs then.
