- Well, next time my dad comes down, I'll send him your way. He is one
- of 3 sets of Identical twins (3 sets of identical boys, one girl, and
- another boy are the total family).
-
- He Rodney and his bother, Roger ended up with identical Drivers license
- numbers for the reasons cited above... neither of them thought to check
- their numbers and neither them (or the state) notices the duplication...
-
- until one day my father, after recieving a ticket for something (his first
- and only ticket when he tells the story =), recieved a letter from the
- state informing him that his license had been revoked for three tickets
- in under a year... it seems that his brother Roger had gotten two tickets
- and the identical license numbers caused the state to revoke my father's
- license (Roger's license was not revoke.. however, I assume that had
- my father gotten the second ticket, and Roger the third, then Roger's
- license and not my father's would have been revoked).
-
- Needless to say, then now have different license numbers.. albeit by
- one digit (I'm not quite sure which one 'tho).
