This sentence is generic enough to be uncopyrightable, too.

Who is believed to have the copyright for this sentence?

There's just one single search result (not really a big surprise):
X-Japan

While we are at it, since you (Persoctreow :) are essentially the head admin now that Trang is busy with greater things (more power to her), I believe I may ask you directly to consider removing the copyright tag from the following sentences as well:

#278461 - too generic (Star Wars again)

#5147042 - too generic once you add proper punctuation

#5148914 - too generic I believe, even if it does have a source

#1766492 - are short quotes really copyrightable? this comes from a sports article which referenced an interviewed player saying this phrase.

#4547967 - same thing, this pops up in a transcript of a TV programme as a quote from one of the participants

#573901 - too famous, lots of generic uses

#4547953, #3945074, #3945091, #3923636 - too generic

#322766, #5699105, #4954836 - more questionable but still too generic imo

#1019827 - this apparently comes from a personal blog which has since been scrapped (page unavailable); surely we needn't worry about copyrighting random posts and comments over the Internet especially when the original source is dead.

#3320176 - bit of a personal request here, but same rationale as above: it's part of a comment on an online blog, would we not copyright user utterances please... (I've sourced quite a few of my sentences from online comments actually, they make a great pool of the living language in its rawest form)

addendum: also you can unred #5147045, the copyright is dead since Twain died over 100 years ago.
