Spelling bee nightmare

"If you don't know the difference between their and they're, your a dumbass"

You're.

That was the joke, thus the quotation marks.

Well. Woosh.

What accent do you have that can differentiate those words by pronunciation?

I have an Indian Accent, assuming that I am from there.

With everyone else included with awake_ash's joke I got a good laugh thanks!

You shouldn't need any specific pronounciation to know how to write these three words, at leaast when you're competing in Spelling Bee. In the international phonetic alphabet they'd all be written ˈðɛr anyway.
