A funny coincidence

Me and my partner (Bootsie) are 17 days apart in age.

I like to to tell people that 17 days after I turned 17, Bootsie turned 17 on the 17th.

Then, 18 days after I turned 18, Bootsie turned 18. ... On the the 17th.

You see on a leap year, we are 18 days apart in age, as my birthday is on the 28th of February. I've always found it cool.

You guys got any similar funny coincidence's?
