You know what's a stupid word? Isthmus. Who comes up with these abominations? How the heck are you supposed to make the sthm sound? I guess you should just pretend the th isn't there when you're saying it out loud, but in that case they shouldn't even have put it into the spelling in the first place. Whenever I encounter this word I'm mentally pronouncing it in my head and feeling retarded, or like I have some kind of mental lisp.
