LOL, I never made the connection.
Last year my aunt and cousins came over for thanksgiving, and my aunt was telling us how she had been waking up very early lately for no reason, at 4:20, she said, every day she'd suddenly wake up and look at the clock and the clock read 4:20. I said "4:20, huh?"... well her kids got a good giggle out of it, but she of course had no clue.
The FDA made fools of themselves on 420 and this approval simply solidifies it.
I wonder if she has made the connection since then?
