What do you mean by "00544" and "44944"?

The boss told the secretary to go out and buy a good license plate. It is better to have a serial number or many eights, but the director bought a license plate of 00544. The boss was furious, and the secretary explained, boss, if you install this license plate, no one will dare to hit you. Look at this license plate, which means "let me try". The boss was overjoyed when he heard this, and then he was hit when he drove out that day. The boss is in hospital, and the secretary is puzzled. The boss said that the license plate number of the car that hit him was 44944 "Try it" ~ ~

It's classic! !
