Poems That Don't Rhyme

Do you ever get frustrated with poems that don't rhyme where you want them to? Here's a litmus test for ya:

Spider, spider, on the wall,
Don't you have any sense at all?
Don't you know that wall's just been plastered? --
Get off of there, you dirty little spider!

Or how 'bout this song ...

Matches, matches, M-A-T-C-H-E-S;
Matches, matches, M-A-T-C-H-E-S.
You can strike 'em on wood, you can strike 'em on glass;
Once I even knew a girl who could strike 'em on her shoe.
Matches, matches, M-A-T-C-H-E-S.

Doggies, doggies, D-O-G-G-I-E-S;
Doggies, doggies, D-O-G-G-I-E-S.
Two little doggies were lyin' in a ditch;
The one was a male, and the other was a female.
Doggies, doggies, D-O-G-G-I-E-S.
