Two horses are talking before a race.
One horse says to the other
“I don’t know what’s going on, right before a race I always get this sharp jabbing feeling in my flank.”
The other horse says
” Yeah, that’s strange. I get the exact same feeling before a race too!”
Right then a dog passing by said
“You idiots, that’s a hormone shot to make you run faster.”
The first horse is amazed and said
“Hey, that dog just talked!”
