Look, I'm going to level with you. Two of the signs in this gallery aren't actually chalk signs.
This sign is less funny and more a statement about how much the sign owner values sarcasm. JOKE EXPLAINED?
The 'sorry' addition is what is funny about this sign. Signs are designed to state information clearly and professionally and the 'sorry' gives the sign a human element that is uncharacteristic. JOKE EXPLAINED.
I count two ways that this sign is inaccurate. Guess both of them in the comments.
This is one of the two. It references chalk signs so I think we're cool here.
My knowledge of what is and isn't a chalk sign is why they hired me at Break
This is the sign in question by the way. I think it's funny enough to include in this gallery, but It's technically not on theme.
This sign is funny because a warning of this nature is largely superfluous. JOKE EXPLAINED.
