My humble attempt at creating a funny one:
YOU CANNOT PASS!!!!!!!
Gandalf? Gandalf the Grey?
Bill? Is that you? What have you been doing all these years?
Oh, you know, killing dwarves, terrorizing orcs, and so forth...
*Gandalf addresses the Fellowship* Hey, everybody. Meet Biil the Balrog. We're old friends. We went to school together.
Nooooooo!!!!!!!!
Hey Bill, do you want to join the Fellowship?
Meeeeeee? I'm flattered!
I hope it's okay and at least moderately funny. Part 2 to follow soon.
