It took me WAY too long to get that. I am just not good at Scrabble-esque games. My brain apparently doesn't work that way O_o. If you ask me for the definition of a word there's a good chance I'll know it, or that I'll at least have heard it before, but I can't for the life of me actually pull up words at random unless I'm trying to actually communicate something. I also can almost never figure out even the simplest of word scrambles. XP
My 13-year-old brother hasn't heard of Muse, but he's heard of Alkaline Trio. Huh? O_O
Edit
*sigh*
Brothers. XD
