If there's one thing that hasn't yet been advertised on late-night television, it's a cream that will shrink your vagina into a tiny nothing that not even an ant could get through. A cream that works miracles to turn even the biggest sleeve of wizard into an impenetrable fortress of solitude. Now that's changed.
Congratulations! You've made it past the words "Vaginal Tightening" without passing out. That or you have passed out, revived yourself and are carrying on regardless. Either way, you have demonstrated great bravery and are an asset to your house. Ten points to Gryffindor!
