April 2 is National Peanut Butter and Jelly Day. This food holiday is a classic favorite of many, and for good reason. The average American will eat over 2,000 peanut butter and jelly sandwiches by the time they graduate from high school. Hum, that’s a lot of sandwiches. Guess Hubby’s not the average American because he’s never eaten a Peanut Butter and Jelly Sandwich even once. Strange man eats Peanut Butter and Butter Sandwiches.
