Srsly make an option allowing you to actually laugh rather then Bluff because I laughed RL at some of his jokes they where funny especially the interrupting cow and the Banite farmer one. and Thunderwear! Get it!? These jokes are funny the option to actually find it funny should be on their rather then to Bluff.
[With a lower reward, of course, as he sees your actual mirth, and figures he doesn't need to pay you as much since you should be paying him.]
Da. Lower reward, but still something for being honest.
And yes Dr. D, they are rather funny. The first time.
I was really peeved when I had to bluff liking those jokes with a gnome.
