One day Ron decided to go swimming, but he couldn't find his trunks. But he REALLY wanted to go.

"Hmmm…" thought Ron, "If I went in my spunkiest undies – no-one would really notice"

So he went to put on his pair of maroon, woollen undies his mum knitted for him. They might've looked itchy, but it fact they were quite comfortable.

Grabbing his towel he went down to the lake.

Almost everyone was down there. It seemed to be the best place to be in the sweltering heat.

Of course, Dumbledore saw this as a good idea, so he netted off a part of the lake for the giant squid to roam around free.

Throwing his towel on a rock, he quickly got into the lake, before anyone could see, his woolly undies. Hermione swam up to him, in a cute light blue bikini. "Hey Ron, took you a while to come! Come on the diving board with me and Harry, it's way fun! It's a bit high, but so cool! And the water doesn't slap your thighs either!"

"Um, I think I'll pass"

"Ok, then, suit your self" And as quick as ever Hermione got out and waited in the line to so on the extremely high diving board

Swimming around, avoiding people, Ron didn't realise that his woolly undies, caught on a pointy bit of seaweed, and was slowly untangling.

Suddenly out of the blue, Harry dunks him, "arrgh!" shouted Ron, (which actually sounded like garrghghghgh – cause he was under water).

Harry cracked up laughing; he was in spunkier board shorts, and didn't mind showing of his washboard abs. He had gotten a tan, and decided to lighten his hair. So now Harry looked like one of the surfie guys on the beach.

"You jerk! I could've drowned!"

Harry cracked up all over again

"I though you went on the diving board" Ron asked

"Nah, the line was way to long, so I went looking for you."

"Oh, ok"

Harry went under the water, to remove a rock from under his foot, when he saw a surprising sight.

"Ron! I didn't know you liked swimming in the nude!" Harry exclaimed

"W-what?! Oh crap! My undies have unravelled!"

Going very red, Ron was looking around, hoping no one was going to look underwater, near him. (He covered his privates just in case). Harry looked at him strangely, "unravelled? You used woollen undies? How un-co is that! Dude! You are so busted! EVERYONE knows nude day is tomorrow!"

So Ron had to swim around until everyone left, then when everyone did leave, he realised someone took his towel. Looking around, he ran out quickly, hoping to not get noticed, but accidentally forgot about the Quidditch practise that afternoon, and streaked across the Quidditch patch.

"STREAKER" everyone yelled

Ron went bright red, ran away and hoped no one knew whom he was.

Dumbledore, sighed and whispered to Professor McGonagal, "I knew we shouldn't have allowed nudists to come to Hogwarts!"
