Don't I remember David Walliams saying "I can't be with you today, as I am busy taking heroin - be careful, it's a little moreish" in the guise of Lou Reed, at the 2002 NME Awards? (I can't find the clip, but here's an online citation).
And didn't Harry Hill famously have it as part of his act? This popular meme certainly thinks so...
this blog seems not to even need to mention its origin. And it's already made its way onto a popular range of t-shirts:
Here's a forum where Russell Brand's being slagged off for using the gag, and here you can see Superhans in Peep Show saying it, but about crack.
It's so common, some people use it with no sense of irony. And here the Telegraph has decided, again with irony-filter off, that it's cocaine that's moreish.
And here's someone using the gag in a review about a football book.
Urban dictionary even uses the gag as the dictionary definition of Heroin!
So the lesson we've learned today is, the "heroin is very moreish" gag? Well it is very - oh, you were ahead of me.
UPDATE: I'd like to apologise to cartoonist Jonesy, from whom I've received the following message that he'd like me to pass on :
Hand on heart, I had never come across this gag before. I'm not the first person to accidentally reinvent the wheel and I'm sure I won't be the last.
One thing I am sure of is that I don't need to resort to plagiarism to get my work published and I definitely don't need to "go online to find the next gag to sell to Private Eye".
