How many did you have?A Roman centurion rides through the night, heading home from a party. A police officer stops him.
Centurion: What seems to be the problem Officer?
Officer: Good evening Centurion. Constitutio and license please.
Officer: Speeding, were we over there?
Centurion: I was riding at the speed limit, Officer.
Officer: Are you returning from an orgy? Looks like you have been drinking.
Centurion: No, Officer.
Officer: How many are these (shows the index finger)?
Centurion: One (I)
Officer: How many are these (shows index and middle finger)?
Centurion: Five (V)
Officer: Ok. Go home and ride carefully.
If you don't get it you probably need to revisit roman letters.
