The numbers represent letters of the alphabet; 4 is D, 9 is I, and so on. These numbers spell "dick".

The rule of 4 and 9 is a general unspoken rule in the United States between drivers and cops. The basics is you don't get in trouble for going 4 or less over the speed limit and usually a warning if going 9 or less. 10 miles invokes fines if caught.

the exception is at the beginning or end of a month when the cops are trying to fill their ticket books
someone else come up with a good example for the rule of 4 and 9

Get a rule of 4 and 9 mug for your dad Callisto.
its a way of writing the number "127'
these arent random
some of you might notice a pattern
1+1 is 2 so you do
1+1+2 which is 4
1+1+2+4 = 8
1+1+2+4+8 + 16

when you get to 16 break it down to single digit and add them seperately so
1+1+2+4+"1+6"
you will get 23 so

1 + 1 + 2 + 4 + 8 + 1 + 6 + "2 + 3"
repeat
i suck at explaining things
did you know 1+1+2+4+8+1+6+2+3+2+8+3+8+4+9+6+2+7+0+7+7+9+1+1+0+1+1+3+1+7+1+1+5+1+2+2 is a way of writing 127
