No, not all rhyming poems are good.

Ringadingadingdong, want a song?
See, with a song, you can't go wrong.
A song can be mighty like the great king kong
Or simple and precise like the beat of a gong. (well no, not really)
A song can be full of words that are long,
Perhaps even have the odd dipthong.
But all can agree that a song is lifelong,
Carried for generations along.
Sure, the singers aren't all headstrong,
Miley Cyrus, caught smoking a bong,
But the song itself, it shall always belong
Whether by the Nile, or by the Mekong,
Or down in Peru or up in Hong-Kong.
Nevertheless, i can no longer prolong,
For this stupid little rhyme cannot be yearlong,
Because i must attend a game of ping-pong,
Of which i'm sure, will accompany a song.
