Do I laugh or should I smack him?

Tim and I had to speak in church on Sunday, this is how Tim started his talk . . .

" I am just throwing this out there, I dated Jimmer's older sister.  Things didn't work out and I am very happy I married Collette and we have 2 great kids.  But I did give you Jimmer for you."  (Something like that)

Thoughts???  Yes he did date Jimmer's older sister.  He had actually just got back from visiting her in New York when we met, and took her out on a date once she came back to school, but I ended that one quickly.  I was just shocked by the comment. :)
