Green Eggs and Ham/Headscratchers

I just realized something...SAM-I-AM IS A FREAKING MANIAC!
 * Thank you Captain Obvious.
 * Considering that a sane person would just find someone else to offer the dish to, I concur, unless Sam has an ulterior motive.
 * He's a drug pusher.
 * Not meaning to be a Knight Templar, but aren't you reading somewhat disturbing meanings into a children's book? I always sort of saw it as a story with the moral that you won't know if you like something until you try it. Granted, Sam does carry on with this more than a real person probably would, but how else are you going to fill a book and get all those rhymes in? Again, not meaning to be overly zealous, just saying.
 * Sam is that annoying kid from school who would never stop talking to you.
 * Sam is trying to get Sam-I'm-Not to accept the part of their food supply that was dyed green in a storage accident, so that he will be able to survive until it's safe to leave the bomb shelter.
