double duh
Triple Duh! (Sorry, just wanted to join in the DUH pattern! )
Quadruple duh!!
quintuple duh....................(sorry I was gonna say 5 duh bu that doesn't sound right :p)
Now that was clever. All trick teasers should be like that. Clever, accurate and subtly deceptive. Of course I fell for it didn't I?
Hex duh? (hexagon)
(I thought it was good)

I was thinking the trick was how many people don't know that a light-year is distance rather than time.. a rare good trick teaser!
i got the sun bit, but surely the sun won't always be the closest star to the earth. what happens if another moves closer? or once the sun burns out?
I'd say that if another star got nearer to us than the Sun we would not be here to know about it!
whoever din't know that one should be in a mental institution
i just read the last 5 words and knew it. i think that helps with trick teasers. fun and easy
sextuple duh is "6 duh." so now, septuple duh!
its pretty easy
Octuple Duh.

You duh-duhs need to check your high school science notes! At least you're learning a few prefixes! We're up to nanoduh, btw!
I thought this was a good teaser because it disguises something well-known (or that should be well-known) in a tricky, kick-me-coz-i-shudda-known context! Well done.

Decaduh!
Just kidding, excellent teaser.

Well however much you guys appreciate it, I think that in the teaser itself there is improper use of the word 'which'. 'Which' is used when the available options have been specified already, therefore the answer could not be the Sun. it would be better if 'what' was used instead.
wait wtf ok never mind i had a mind blank
to make up for it: undecaduh!!!
