Invisibility Cloak Jokes

Why did Severus Snape cross the road wearing an invisibility cloak?

So no one would know what side he was on.

I was given an invisibility cloak by my grandfather, but it was stolen in 2013. After investigating this issue, I have come to the conclusion it was Robert Lewandisney.

That's why he was invisible in every big game since 2013. SHAME ON YOU LEWANDISNEY!
