Just posting a link to a facebook group. No need to join, just read the gist of it. It's funny.

The group is called:
The hilarity of Harry Potter quotes when changing "wand" to "willy"
Some examples are:
- "There was a moment, in the graveyard, where Voldemort's willy and mine sort of... connected."
- Draco whipped out his willy, but Harry was prepared and his willy was in his hand before Draco could react....
- "Snape lay panting on the ground. James and Sirius advanced on him, willies raised..."
- "As you can see, we are holding our willies in the accepted combative position."
