This is funny to me...

I'm taking a photo, of someone taking a photo,

that's taking a photo, of some people in the background, 

that are taking photos

Photographers don't like to have their photos taken,

and will often use their cameras as a cover to having their photo taken

I know this because I do this :) 

See, he just won't let me take his photo, which is ok,

because at this point no one else was ready for the shot either!

His stance  cracks me up...which was why he did it :)
