Don't be angry TC.
I watched the show and saw people that have couponing as their only hobby in life. I personally enjoy having a variety of activities although MBs take a fairly large chunk.
I wouldn't be able to be an extreme couponer due to the fact that, for the most part, I don't eat the foods that have coupon offers. Almost 50% of my weekly grocery bill is for fresh fruits and vegetables. Sometimes there are good store deals and even store coupons, but you can't hoard fresh foods without canning.
