Well, the people at BIG National Holidays wants us to get fat today.... Because it's National Double Cheeseburger Day! What's your go-to place for a good burger? Today is also National Linguine Day! Linguine dates back over 400 years, and is one of the world's oldest kinds of pasta. Rightfully so - It's delicious! Finally, on this day in 1978, 36 year old Muhammad Ali boxes and wins against Leon Spinks to earn his 3rd heavyweight boxing title. He's the first, and probably only boxer, to ever do so!
