Afroman, "Because I Got High" (2000)
This nursery rhyme–style sing-along reportedly took Joseph "Afroman" Foreman only two minutes to write, and subsequently launched a career that glorified the pothead slacker lifestyle. Though "Because I Got High" remains the West Coast MC's only major hit, it's arguably one of the best-loved weed songs of all time. After all, who hasn't forgotten to clean their room, cheat on their final exam, pay their child support, etc., because they got high? "'Because I Got High' put me on the map – it's what got me a record deal, a Grammy nomination and made me a household name," Afroman told Rolling Stone in 2014, just as he released an update of his novelty classic for the legalization generation.
