15. Macaulay Culkin’s “Pizza Underground”

Macaulay Culkin is another candidate to top the list of weird things celebrities do while high.

From getting arrested on a regular basis, to denying taking drugs for as long as he could, Culkin is the exemplar of how inappropriate wild underage partying and drug abuse can destroy a young and prosperous life.

Nowadays, Culkin actually has a band called “Pizza Underground”, which does live shows and performs songs about – pizza.

As bizarre as this may sound, Culkin’s music shows are actually attended by real life fans, although the band was recently booed in Nottingham and thrown beer cans at before cutting the show short and leaving the stage.
