I think the tie demonstration is far more superior than my pineapple boat one. I actually remember the lines. I personally feel that the tie one is easier to do than to cut the pineapple. Also, I'm much to lazy to go out and buy a pineapple and then bring it to school. It's such a bother. I prefer the tie demonstration to the boat one since it's the freshest one in my head right now and I don't want to ruin my grade even farther than I have. Tie demonstration is my choice for the next cafeteria speech demonstration.
