- Adding a few more 1. The vital amino acids- Pvt. MT Hill never tires- Proline, Valine, Threonine, Methionine, Tryptophan, Histidine, Isoleucine, Leucine and Lysine.

Some versions have it as Pvt. Tim Hall always argues, never tires.- Same as above, with the following: A is always argnine, and T is threonine and tryptophan, never tyrosine.
