1. Sandwiches are named after an actual British Earl. In 1762, John Montagu, the 4th Earl of Sandwich, didn't want to leave his card game table to eat dinner. He asked his servants to bring him slices of meat tucked between two pieces of bread so he could eat with one hand while keeping his cards clean!

2. The world's largest sandwich weighed as much as a school bus. In 2005, a team in Michigan built a giant corned beef sandwich that weighed a whopping 5,440 pounds! It used over 2,000 pounds of bread and hundreds of pounds of cheese and meat.

3. Peanut butter and jelly was popularized by soldiers. During World War II, the US military included peanut butter, jelly, and sliced bread in soldiers' daily ration kits. When soldiers returned home from the war, PB&J sandwiches became an instant hit with kids across America!

4. An open-faced sandwich has no top bread. In European countries like Denmark and Sweden, traditional sandwiches called smørrebrød use just one slice of dense dark rye bread on the bottom, with beautiful arrangements of fish, cheese, and veggies stacked on top!

5. The submarine sandwich was named after real military submarines. Long, stuffed Italian hoagie rolls got the nickname "submarines" (or "subs") in New London, Connecticut—a town where navy yards built real underwater military submarines that were shaped just like the long bread rolls!

6. Americans eat over 300 million sandwiches every single day. That is enough for almost every single person in the United States to eat one sandwich every single day of the year!

7. Elvis Presley loved a sandwich with bananas and bacon. The famous singer "King of Rock and Roll" loved a grilled sandwich stuffed with creamy peanut butter, sliced bananas, and crispy fried bacon strips!
