My Mum and Dad just sent me some photos of a family holiday we just had together (them, me and DH, and DD who is 7 months old). It's one of those online ones which you can view as a slideshow.
My Dad (I know it's him and not my Mum from the way it's written) has captioned each photograph, writing as if my DD has written them. "Here I am with Mum at the beach" and "Me on a walk with Grandma and Grandpa - looks like the old folks are getting tired here!". You get the gist.
There are some photos of DD in the pool. There of one of DD and me, where she is wearing her full body suit for sun protection, and DD is not looking very impressed. Underneath my Dad has written "urgh, here I am stuck in a boilersuit while Mum gets to wear a bikini - not fair!" So far, so drole.
The next 3 photos are of DD in just her swim nappy. Her chest is visible rising out of the water.
In the first one, he writes "Here's me with Grandma - luckily she saw sense and let me strip off!"
The second one is him and DD. "Granddad even let me go topless!" 
The final one is of both my parents with DD and says "Here we are posing for Playboy magazine - Miss August, Playgirl of the Month!"
Now. I KNOW he meant nothing weird or pervy or strange by this. He was trying to be funny. I am 100 per cent sure of that.
But don't you think that is an extremely strange thing for a grandfather to write about his granddaughter? I mean, of all the things to write.. WTF???
To make matters worse, I suspect this online album - with the inane comments - will also be sent (or already has been sent) to wider members of the family, aunts etc.
This is more of a WWYD rather than an AIBU, but how should I handle this? What, if anything, should I say to him?
