No a real cow has not jumped over the moon
No a cow can not literally jump over the moon. it was hard enough for humans to get to the moon with a rocket.
With a trampoleen!
According to one theory, the rhyme is a lesson in astronomy, Hey diddle diddle, the Cat (Leo - the Lion) and the Fiddle (Lyra - the Lyre), the Cow (Taurus - the Bull) jumped over the Moon (the Moon); the Little Dog (Canis Minor - the Lesser Dog) laughed to see such sport, and the Dish (Crater - a dish shaped constellation) ran after the Spoon (Ursa Major - the Big Dipper).
It is only a nursery rhyme, a cow didn't really jump over a moon. It is just a made-up poem. :-)
If you are referring to the real moon in the sky other than it's reflection or a toy, then yes, it is impossible for a cow to jump over the moon
Fiddle
Yes, the cat with the fiddle told me he could.
Why did the cow jump over the moon? Because I told it to, and by the way, it couldn't even reach the moon. --- Why did the dairy cow jump over the Moon? The farmer had cold hands. --- What did the cow manure farmer name his daughter? Patty. --- Why do cows wear bells? Because their horns don't work. __ Knock knock? Who's There? Interrupting cow! Interrup.... MOO!!!!!!!!!!!
