I saw Harry kissing Dumbledoor

I saw Harry kissing Dumbledoor
Underneath the mistletoe last night.
He didn't see me creep
Down the stairs to have a peep;
He thought that I was tucked up
In my bedroom fast asleep.

Then, I saw Harry tickle Dumbledoor
Underneath his beard so deathly white
Oh, what a laugh it would have been
If Ron had only seen
Harry kissing Dumbledoor like that.
