spranks are usually pretty tight, except at times can be tools the size of a bulldozer. Which are pretty fucking big. Spranks remind me of a big huge happy bear, like Winnie the Pooh. Except Winnie the Pooh saying some really dumb shit, having awful comebacks, and (hopefully) wearing more than a red shirt. In all, it's good to be a sprank.
