A Daddy's Pride

I thought this was a bit embarrassing, but of course his daddy took great pride in this little story:
We were at the store day after Christmas (stupidly, I know, but we needed milk) so of course it was packed. Carson and Trevor mentioned they wanted to go home and watch a movie with popcorn, and started good naturedly arguing about sharing one bag and decided we'd all need our own bag to eat. I told them if we each ate a whole bag ourselves we'd be fat! They thought this was funny and then started competing about who would be the fattest once we were finished.
Carson: "I will be the fattest, because I can eat popcorn faster than you!"
Trevor: (exasperated by the competition at this point, stands up in the cart in front of a store full of people as we approach the VERY long checkout lines)"No! I will be the fattest, AND the tallest, and I will have the BIGGEST PENI!!!!!" (that's as close to grammatically correct as I will let my youngsters go)

He got tons of chuckles and mirthful grins and the cashier gave him a high five. The boy is three, y'all. What am I going to do when he's 15?? And no, we don't have discussions with our children about how having a big "peni" might be a good thing, he's just a boy, and this is possibly genetically inserted along with the amniotic stuff.
