It's not the warm, muggy weather that is starting to creep in and make you sweat all over.
It's not the lack of homework or plethora of school functions four out of the five nights per week.
It's not even the sudden urge to stop eating and drop 40 pounds because OH MY GOSH it's time to get into a swimsuit.
Though that is a serious problem.
How do you know that summer is almost here? These fabulous hair cuts, that's how.
Six years running, people. That is a lot of hair history.
I give you the Mohawk Brothers of 2012.
