Here's a Guinness World Record that is sure to stick in your head for days. And it's just as bizarre as most featured in the book.
A group of 1,500 Canadian students and staff -- kindergarten through high school -- scored the World Record for most people performing Anna Kendrick's catchy "Pitch Perfect" track, "Cups."
In addition to the packed gymnasium of kids tapping away on red and blue solo cups, the video shows them "cupping" in various other places around school.
Sure beats the heck out of math class.
