A cheeseburger with 1 type of cheese is good, but a cheeseburger stuffed with gouda and bacon and topped with American is better. Grill up a few Bacon Gouda Lucy Burgers for your cook-out. Your guests will be thrilled.
Another idea for teaching kids to pick up their stuff. A little drastic but if other things don't work that's what you have to do...just make sure you're actually willing to throw anything out that's still in there or you'll be doing more harm than good! -BI
