Bird brained

"So, yes," Mrs Nunn says.  "Thanks for phoning... Oh, those bloody pigeons are at it again!"

"At what?" I ask.

"They're shagging in the apple tree."

"Oh," I say.  There's not much else to say to that than "oh".

"Also, I think they're both male pigeons.  The male pigeons are having gay sex in our apple tree."

"You think they're both male?"

"Yes.  Or maybe both female.  But they're definitely gay."

"Why do you think the pigeons are gay?"  This is an area I feel needs exploring.

"Well, they shag and they shag and they shag, but they never have any eggs."

Mrs Nunn, doing her bit for gay pigeon rights.
