SCUBA and NASA are always the ones I use against that argument. It would be Skuh-baa instead of scooba, and neh-sa instead of nah-suh.

And no matter what way it was spelled, it’s the only word we’re still arguing about that literally has a song to go with it to make sure everyone pronounced it correctly. It’s pretty clearly a soft g, because it was a marketing trick, not a dictionary word. It doesn’t have to follow any rules of English, just like all those companies just removing random letters and changing ck for x, etc. Flickr, tumblr, Grindr, scribd, Lyft, Kwik, Cheez, etc etc etc. Twitter was originally even twttr.
