“in dead until dark who is bubbu supposed [to be]”?

Pop Culture knowledge is a wonderful thing. The levels of trivia difficulty vary of course, but how can one not know this?
You’re in the southern US, when a supposedly dead guy comes along, who is a little destroyed by the drugs he used to take, referred to as the King and Bubba, not Bubbu. [This is quite definitely a reference to Bubba Ho-tep.]

It’s Elvis, of course. Hope you could learn something.

And now, although it isn’t actually a question, I have something to say to this:

“how to get a macgyver haircut season 5”

You don’t. Seriously. MacGyver is  a great guy, but his haircut – no matter the season – really sucks.
