I'm going to disagree with Equinox Chickerydooda and say that every line is the best line so there!
I'm going to disagree with Theo Paleye, and say the best line in this is 'Extemporaneous' because the way that word is used just made me want to hug myself with Gred and Forge glee. They are such marvellous characters and you have caught their mischief and joie de vivre in such a fabulous poem. This just catches who they are/were incredibly well.
Well done. I loved this at the time and love it still mainly, I think, because the use of language has stayed with me long after I stopped reading. ~Carole~
I love, love, love the way you aced this form, Minna. You are always so good at using structure to its full advantage so I'm not surprised with how well you did with the challenge. This does exactly what a double dactyl is meant to do: be silly and make people laugh. It perfectly matches the attitude of Fred and George. I particularly love the phrase "meddlesome japes".
