Seen here performing two simultaneous ghost handjobs, this is a short video of everyone's favorite hotel owner Basil Fawlty (John Cleese) explaining why stupid people are too stupid to know they're stupid. Apparently you actually have to have a little intelligence to know you're stupid. I, for one, am smart enough to know how dumb I am, and I'm okay with that. I'm still smarter than all my friends.
Keep going for the video.
Thanks to Jeff K, who isn't stupid at all, at least not by dog standards.
