How do I parse this phrase from a limerick?

This is a limerick I've taken from "The Wordsworth Book of Limericks".

It's published in this form in many other books and also all over the internet.

To his bride said the lynx-eyed detective,
"Can it be that my eyesight's defective?
Has your east tit the least bit
The best of your west tit?

Or is it a trick of perspective?"

I'm having trouble parsing the lines in bold.

Does "the least bit" mean "slightly" here? Or maybe "has" means "does … have?" Or "bit" is the past participle of "bite"?

None of these readings make any sense to me.

What does this phrase mean?


Solution 1:

I think the line break between the 3rd and 4th lines both makes the sentence difficult to read and that difficulty/ambiguity is a part of the humor.

  1. has your east tit: is your east tit
  2. the least bit the best: a little larger/longer
  3. of your west tit: than your west tit
