Husband and Wife get holes in one

I got my first hole in one on 2-12-14 at Jacaranda West Country Club on hole #2 using my 7 wood from 123 yards. Earlier that day, my husband got a hole in one on the same course on hole #13 from 166 yards using his 4 hybrid. What are the odds that a husband and wife would both get a hole in one on the same course on the same day? Both hole in ones were made using Titleist balls. I use the Velocity and husband used a PROV1x.
