In case you didn't know this: The Offspring's Dexter Holland is a Doctor. Really!
Holland got a PhD in molecular biology in 2017 and jokes in an interview that, "I insist that my band members call me Dr Dexter!"
Guitarist Noodles chimed in, saying, "It’s a huge pain in the a**. I mean, first of all, lead singer disease and then you go and give him a PhD, come on!"
Holland joked, "It’s true, whenever I don’t agree with them on something I just ask “who has the doctorate here, oh, right it’s just me…”
