Behind me in a boarding line the other day a woman had this button on a purse: “The only obstacle to happiness is reality.”
A woman waiting for this particular flight has a shirt that says: “I’ll try being nicer if you try being smarter.”
One of the TSA screeners added to the standard laptop/video camera/shoe announcement: “If you can rebuild a Buick with your belt buckle, you may want to take that off.”
