Happy 4/21...or is it 4:21....or is it 421?

Happy 4/21 all!

It's the strangest thing....I went to Kroger today to get a few things today and noticed that the entire snack cake and cookie aisle was sold out.  No Ding Dongs, no Ho-Ho's, no Twinkies, no Cupcakes, no Suzy Q's, no Snoballs, no Zingers,  no Oreo's, and no Funyuns....nothing!
Did I miss something?
