Codebreaking

The verse following has been disguised by applying a simple substitution code. Each letter of the alphabet in the original has been replaced by a coded equivalent wherever it occurs, although in some cases a letter is substituted for itself. The full punctuation has been retained to provide a few clues.
Can you break the code and read the verse?

To the man-in-the-street, who, I'm sorry to say
Is a keen observer of life
The word intellectual suggests
Straight away
A man who's untrue to his wife.

Technically, though, that was a cypher, not a code 😀
