We have several of these throughout the year in the U.S., though the exact kind and number varies a bit depending on where you live -- Canada Day, for instance, is celebrated so subtly in most of the States that if you missed the temporary addition of French on many signs and labels, you might never notice.
Still, most of 'em are well-meant. Most celebrate the great tradition of turning whatever your grandma ate into fast food and most of that turns out pretty tasty (if not always as healthy as the original); I am , however,withholding judgement on October's fried-sauerkraut-on-a-stick.
As for me, I'll have my slingshot out this afternoon, trying to take out an almost-empty bottle of Hellman's floating in a kiddie pool: Sinko de Mayo!
