From the sheer number of burger joints in this country, it's easy to tell that Americans love cheeseburgers.

In the Caldwells, you can get everything from Wendy's and Five Guys to the winner of the Patch Readers' Choice Poll for Best Burger: the Cloverleaf Tavern.

To celebrate National Cheeseburger Day, here are five fun facts to bite into:

1. The largest cheeseburger ever made in the world weighed in at a whopping 777 pounds. Created June 2, 2011 at the Alameda County Fair in California by Juicy's, the giant burger also featured 50 pounds of cheese. The bun alone weighed in at 272 pounds. Complete coverage of the event (including pictures) can be found here.

2.  Although temperatures are expected to dip slightly over the next week, it's still not too cold to fire up the grill. Thirty new cheeseburger ideas like the "The Johnny Appleseed," which features aged Wisconsin cheddar, maple bacon, sauteed apples, whole grain mustard and red onions on sourdough, can be found here.

3. The popular Jimmy Buffett song "Cheeseburger in Paradise" was inspired by a boat trip Buffett took. Hampered by bad weather and tired of the canned food and peanut butter stocked aboard, Buffett found himself continually craving a cheeseburger. When the boat finally docked on the island of Tortola, Buffett was able to order the cheeseburger he had been fantasizing about.

4. Anyone remember Mayor McCheese? The giant cartoon cheeseburger served as the bumbling mayor of McDonaldland from 1971-1985. A lawsuit against McDonalds over the character's resemblance to H.R. Pufnstuf was settled in 1977. Now he has his own Facebook page.

5. But you don't have to eat meat to celebrate National Cheeseburger Day. If you want to make your own patties, here is a "Best of Everything" veggie burger recipe.
