I still laugh when I see anything that has to do with Napoleon Dynamite...the first time I watched it was during a holiday break with my brother-in-law and my dad at like 12:30 am. We were quite punchy and laughed really loud. I think G-ma Pen told us to quiet down about 4 times.
I was sent a link to an advertisement that the Utah State Fair used a couple years ago. Super funny.
