Watermelon nature's Viagra? Just remember to spit.

Just in time for the Fourth of July holiday, the Associated Press reports that researchers have discovered that watermelon "has effects similar to Viagra." (Now you know why this man, to the left, is smiling.)

According to the AP story: "Watermelons contain an ingredient called citrulline that can trigger production of a compound that helps relax the body's blood vessels, similar to what happens when a man takes Viagra, said scientists in Texas, one of the nation's top producers of the seedless variety" [and polygamy central. Gee, I wonder if there is a connection?]

The only problem is that you would need to eat at least six cups of watermelon (preferably the yellow-fleshed variety) to get the desired (ahem) effect. And, wouldn't you know, watermelon is also a diuretic. So you'd probably wind up spending more time in the bathroom than in the bedroom. (Though I doubt that will stop some guys from smacking down on some nice, fresh, juicy melons this weekend.)

So ladies, if you want to get some rest this weekend, I recommend you tell your man that when it comes to watermelon, just say no -- or if he must indulge, remember to spit, not swallow.

And with that I wish you all a very happy Fourth of July holiday.
