Who wants to buy a dictionary?

So I'm watching "Who Wants to be a Superhero?" the other night. That's Stan Lee's reality show. For years, Stan Lee has been saying "Excelsior!" It's a pretty cool thing to say, very up with people. During the show, Lee explained to the people on his show that excelsior is an old English expression that means to do your very best. A little disappointing for me since you'd think a guy who's been saying a thing for 50 years would have had a chance to look it up in the dictionary before defining it on national TV. I thought any fool smart enough to know the word would know it's not English. It doesn't even sound English. Why would anyone assume it's English. Good way to tell it isn't English? You need to translate the word to know what it means. That's your first clue. Not a lot of English words you need to translate into English. Does this show not have a producer, a director, a script girl or a dictionary. Other than that, it's pretty cool. ex·cel·si·or Pronunciation: ik-'sel-sE-&r, -or Function: noun Etymology: trade name, from Latin, higher, comparative of excelsus high, from past participle of excellere : fine curled wood shavings used especially for packing fragile items
