In this day and age, you’d think everybody would have some sort of idea what 4/20 is, but not everyone is apparently hip to the lingo.

He then had to explain the meaning behind everybody’s favorite marijuana-themed holiday. We might just be paranoid (cough) but maybe this “sleep specialist” was Dr. Mary Jane?
