From mel....

 

Went for a walk with my new girlfriend and we saw dogs mating.

She said: "How does the male know when the female is ready for sex?"

I replied: "He can smell she is ready. That's how nature works."

 
We then walked past a sheep field and the ram was mating the ewe.

 
Again my girlfriend asked: "How does the ram knew when the ewe is ready for sex?"

 
I replied: "It's nature. He can smell she is ready."

 
We then went past a cow-field and the bull was mating with the cow.

 
My girlfriend said: "This is odd. They are really going at it. Surely the bull can't smell when she is ready?"

 
I said: "Oh, yes; it's nature . All animals can smell when the female is ready for sex."

 
Anyway, after the walk, I dropped her home and kissed her goodbye.

 
She said: "Take care and get yourself checked out for Covid-19.

 
Surprised, "Why do you say that?" I asked her.


She replied: "You seem to have lost your sense of smell."
