I ask you.

You leave them alone for a couple of seconds and look what happens. Newleyweds. I suppose we can't blame them. Which leads me onto the honeymoon. Why is it called "honeymoon?"
The explanation is laughably simple. The couple are really sweet so that's why it's honey. And, especially in olden days, it was often the first time the groom had seen his wife's naked bottom. From which we get moon.
Thus Honey Moon and from there Honeymoon.

Newleyweds eh? They can't wait.
