I've always heard (well, seen) "think", have only seen "thing" in casual internet usage and I consider "thing" to be wrongity wrong and nonsensical. The One True Idiom ("think") makes perfect sense— using "think" as a noun here is the kind of minor wordplay that, istm, is common in this kind of phrase— but the False Heretical Corruption ("thing") makes no sense. Why would you say "another thing" without a previous thing as a referent? Why would an 8-foot-tall Wookiee live on a planet of 2-foot-tall Ewoks? This does not make sense! You must acquit.
