What's your problem with the number 16?? Much more lucky than 17 (remember, in many countries they don't have elevators with the number 17 in them).
If Josh really wants to use a 1 or a 7, use a multiple of 1+7...8 or 16.

We've suffered through four years of nothing and all I can attribute it to is this stinking number 17.
It has to end.
