Explain this Xmas cracker joke

[Valaris]

What kind of cough medicine does Dracula take?

Con medicine

WHAT!? I don't get it!?

Should be coffin medicine- typo?

It won't let me upload a picture but it's written exactly how it looks on my OP

Oh no, meant their typo not yours

I just googled this to see if its a typo & there is a news article from 2018 saying people were baffled by the joke, and then goes on to say the jokes has been circulating for at least 3 years - you'd think sainsbury would have corrected it by now?!

It’s famous! It’s supposed to be coffin medicine. I think there’s some typographical reason the two ffs disappeared.

Yup COFFIN medicine, stuff like this happens when outsourced to locations where English isn’t their first language.

The random typo version made me laugh more than the original

It still doesn't work as a joke though, with the lead-in saying "cough medicine", because I wouldn't class "coffin medicine" as a type of "cough medicine".

Maybe if you said "what kind of medicine does Dracula take when he has a tickly throat" (or Covid, would work quite well perhaps?) ?

There was a thread about this exact joke on Christmas Day a few years ago.

You usually have c-off medicine, but instead he has c-on medicine.

I'm not sure why it mentions Dracula, but it makes sense to me.

Yep should be coffin. I read something that it’s something to do with ff being something in a printer’s code and an error reads it in the text of the joke and removes it. We didn’t get one with it this year, quite sad

Oh I found it! Completely not what I said

I've tried to attach the picture again
