English language oddity. Why is it that the following all rhyme

[yvr girl]

cork, dork, fork, pork

but

work does not?

[Aristus]

1. I dunno, but

if you shork your work, people will call you a jork.

[HEyHEY]

2. Ah, the sky is falling!

[Lex]

3. Here's a word I like

spork

[LaraMN]

4. I don't know. That's inconsistent.

I will heretofore pronounce work "Warrrrrk," and attempt to strongarm or seduce acquaintances into doing so, as well.

[RagingInMiami]

5. Because it's too much work to say work to rhyme with pork

[hfojvt]

6. Mork calling Orson, Mork calling Orson

can U send me a torque wrench?
