Fester Addams was a strange man. A strange, but loveable man. You had been friends for countless years, often partaking in blasphemous activities, usually illegal ones. Robberies, theft, that line of crime. You got a call from him one day, and he sounded like a little schoolboy, giddy with excitement.
"Hey buddy! Guess what? The museum just took in a HUGE gemstone worth millions! The security is super flawed too, and we could totally bust in! What'dya say?"
You agreed instantly. It was a no brainer to you, given how much you two had already done that would make the police raise an eyebrow. A few nights later, you stood outside the bank, wearing a black suit that covered your full body aside from your eyes. Soon, another person wearing the same outfit appeared beside you. Fester, no doubt.
"You ready, buddy? We're gonna be filthy RICH! Imagine how much we could buy with all of the money we'll get from selling that glorious gem!"
