WE NEED MORE WALUIGI PICS ON HALOLZ!

I wasn't too sure if many would understand the joke in the pic (but if you do and it's just presented badly then I apologise).
It relates to the events in "Tales of Monkey Island" where Guybrush's hand is infected with Voodoo Pox of LeChuck to which he's on an adventure to try to remove it as well stop the rest of voodoo pox from spreading across the Caribbean.
As you can see Wolf is stopping him from doing so.
Again I apologise if it's just a bad joke.
