1. Which is funnier: Self-depreciating humor (at the very basic form, saying you suck at something when you don't), or falsely egotistical humor (and at it's very basic form, saying you are awesome at something when you aren't)?
I'd have to say falsely egotistical humor owns all. I had never worked out a single day in my life. It gives my friends a kick when I talk about my "guns" and my "six pack".
2. You can be stuffed and overstuffed, but can you be understuffed?
