that's a crazy 7. I might steal that font

I thought it was an F instead of a 6? And the person's writing is great.

You mean the F?

F doesn't come after 5, must be a 7!

It’s definitely an “F”. That’s the inconsistency joke.

6 comes after 5 and the 6th letter is F

Four, five, feven

feight ... fine

Is that an F or a backwards 7

Too inconsistent to say.

Guy must have been there a while...

It could also be an unfinished swastika

I can’t tell anymore. I’ve always read it as a backwards 7 with the middle mark to differentiate it from a 1, but the comments on this post have me second guessing that now.

Let's just say both

FFF - the letter of the feast.

According to my eldest brother, that's the British way of writing it. I don't know if that's true, though.

Well, F is the sixth letter in the alphabet.

Alternatively, it could be fifteen, which is after five.

What, you've got a giant trampoline?

I actually have a maze tattooed on my body (absolutely no swastika allusions) so that bit made me sad.

No. No it isn't.

FFT the Fast Fourier Transform wait what where we talking about again

Well, good to know. That was most likely my misunderstanding rather than his error. Thank you for the cultural clarification!

This was funnier in the 80’s when it first started.

A true antique then! Was there a particular place it started or did this joke just kind of circulate?

I think it just kinda spread.

A mistake plus keleven, gets you home by seven!

In the early 2000s there was a dive bar in Boston and people started scribbling grout puns in the grout between all the subway tiles at the urinals. It was all so brilliant, drunk poets, but I hardly remember them at this point;

Oscar the grout

Who let the dogs grout?

Twist and grout

Grout minds think alike

Etc
