Blended Weiners

Alright. Somebody please explain this to me. Imagine ...

You have just broken your jaw in a car accident. You are facing 8-10 weeks of liquified dinners with your mouth wired shut. Your doctor recommends that you make sure you are getting plenty of nutrients, lots of calories and protein to help your bones heal and prevent you from losing too much weight. Then he gives you a cookbook. The cookbook has recipes such as:

VEGETABLES
1/2 cup mashed potato + 1/4 cup gravy + 1/2 cup milk

Ok. This is a gravy milkshake. I realize there are some extra calories in the gravy. But, potatoes?? Ummm, don't tell the Irish this one, but, you can't live on potatoes. You'll end up with scurvy or ricketts or something. Moving on, we have dinner suggestions ...

Yum.
Weiners with baked beans thinned with V-8 juice.

I wouldn't be caught dead eating this. Let alone blending it and drinking it. Blended weiners. The ultimate in revolting.

Fruit Drink
1 banana or 1 portion canned fruit
Lettuce - 1 large leaf
2/3 cup fruit juice - grapefruit, orange or pineapple

Ok. This one sounds alright. I actually tried it and it tastes pretty good. I recommend fresh squeezed juice. But, somebody, please explain the lettuce leaf? Please?
