Say again?

Words you see in writing, that you'll never hear anyone say out loud:

Indefatigable

Now write it down and show it to the first 5 people you see and ask any one of them to even try to say it out loud.

I'll bet you just tried to say it to yourself and had to try 2-3 times before you got it. Am I right, people? And how many times did it come out as indefaggotable before you got it right?
