|Oh my God, sadorose, this got me laughing and laughing. It took no longer than the second line before I busted out laughing.
It also got me thinking. At first I thought the, "Many chunks were tossed" line was wrong. But then I went back to the song on youtube. The tiny ship was tossed. The tiny ship was tossed! So it works, it works.
Listen I always hesitate to make/offer constructive criticism for pieces (who am I?), but I do have one for this - It would be to tighten it up with the Gilligan's theme song. Your song, it seems to me does not follow the theme song beat for beat or line for line for that matter. For example, you say "Many chunks were tossed." That's missing a couple syllables from, "The Minnow would be lost."
To "fix" this might be simple. Say, for instance, "Many lumpy chunks were tossed. Many lumpy chunks were tossed."
I know what you're thinking. This was a toss off poem, it need not follow the song exactly. But rose, I friggin' loved this. I think it will be funnier if your lab "song" follows the cadence of the theme song beat for beat, cause the reader will be singing it in his head as he reads your changes. That's so crucial to the humor.
Also I wanted your lab characters so bad! I know, just know, that the ones you come up with will be gems. Where's your lab version of Gilligan and the Skipper and the millionaire and his wife? And for Pete's sake, where's the PROFESSOR and Mary Anne?)
Actually it looks like you didn't finish it? Maybe???
Anyway, it's wicked clever and amusing as it is, so you can ignore my suggestion to make it beat for beat and line for line like the song. But it would make it longer, and in this case, I think for this short piece more would be better.
And I'm sure anything you added would get me smiling and laughing like a fool.
