A hyphenated word and a non-hyphenated word walked into a bar.
The barman nearly choked on the irony.
Ba-boom tish!!
Anyone brave enough to explain this one — in writing??

IRONY: Not wrinkled.

(From The Left-Handed Dictionary)
ALTERNATIVE VERSION:
A man with a hyphenated name and a man with a non-hyphenated name walked into a bar.
Both ordered drinks.
Q: What’s the difference?
A: The man with the hyphenated name wanted an extra dash in his drink.
(No ‘Ba-boom tish’... not as funny, but there you are.)
