Legend has it that there is an ancient script that's been lost for years, said to be hidden under a loose paving stone in Bel Air, Los Angeles, which states that summertime has not officially started until Will Smith's Summertime is played.
The script is, at this point, still only a myth, so there's no way of knowing if it's real, but the law it states is all the while relevant.
With that in mind, Will Smith obviously wanted to make some people's summers, so he dropped a live impromptu performance of the '90s classic during an ad break on The Late Show with Stephen Colbert.
As the interview cuts to the break, resident band Stay Human begin to play an instrumental version of the 1991 hit, and of course, Will couldn't help but to get involved.
Much to the delight of the studio audience, the 47-year-old grabs the nearest mic and launches into the first verse.
The crowd lap it up as he clearly still has it.
The Late Show with Stephen Colbert airs Monday to Friday on CBS, every night at 23:35, Eastern and Pacific Time.
