For the most part, food and drink holidays come one per day, but today it's a regular smorgasbord.
Today is National Lollipop Day, National Hot Dog Day and National Ice Cream Soda Day! And that sounds like...well, a stomach ache. I would suggest not eating them all at once but maybe eating them at each meal. Maybe some lollipops for breakfast, a hot dog or two for lunch, and a couple of ice cream sodas for dinner.
Here's a history of the lollipop from Wikipedia, and here are some cool lollipops you can buy from Candy Favorites. Here are some hot dog recipes, including Spanish Hot Dogs and Rice, Joan Lunden's Paprikash, and Hot Dog Ramen. Then make yourself an ice cream soda or two.
