Vitameatavegamin, the TV sitcom tonic of vitamins, meat, vegetables, minerals and alcohol, made a classic episode of I Love Lucy. If you haven't seen it, you're missing one of the funniest routines ever broadcast.
In contrast, V8banana, is a real health drink that sounds awful, but isn't--depending on your taste, of course. It's easy to make, you just blend:
1 ripe banana
1 can of V8 vegetable juice (5.5 ounce can)
3 or 4 ice cubes
What you get is a drink that's not too sweet but a little more exotic than either a banana smoothie or just a straight drink of V8.
