Cover art for Alligator lyrics by Tegan and Sara

You got them pretty close. My corrections:

sensitive it's true alligator tears cried over you over you, over you over you, over you

Run around on me I'd sooner die without run around on me I'd die without

relentless yes, it's true my motor mouth it runs over you over you, over you over you, over you

run around on me I'd sooner die without run around on me I'd die without

over you, over you over you, over you over you, over you over you, over you

run around on me I'd sooner die without run around on me I'd die without

no hissy fits, mind my manners I won't make a scene

oh, oh you over you, over you over you over you, over you

run around on me I'd sooner die without run around on me I'd die without

rotten? yes, it's true alligator tears spilled over you

run around on me I'd sooner die without run around on me I'd die without you run around on me I'd sooner die without run around on me I'd die without

oh! over you, over you oh you over you, over you over you, over you over you, over you oh you over you, over you oh you over you, over you

I'm not sure about all the over you parts. I'm pretty sure most of the time she's saying over you, because in the clip of Tegan singing from it on Jordansilver.com she says it as "over you". But I think in some particular parts she's definitely saying "Oh you." I changed "cry" to "cried" and "spill" to "spilled". Minor corrections, but important just the same. Oh, and replaced "mind over mouth" with "my motor mouth". The last part, where you put "wild", I've got no clue. It sounds like "rotten" to me, but that doesn't exactly seem right. I've listened to this song a thousand times, and this is what I've gotten from it. Kudos on getting the "hissy fits, mind my manners" part, that one has been stumping me for days. Thanks for putting these lyrics up here! Can't wait for Sainthood to drop so we can all be sure!

well rotten does sound closer than wild so I'll leave that =P and I'm definitely stumped over the over vs oh situation, I wish that she'd made it clearer when she performed it xD but as soon as the cd is out that'll definitely be cleared up

there's a LOT of "I'd" that you added that's not actually there.

note: original posted lyrics for alligator, the cure, the ocean, on directing, red belt, and hell were based on the rifflandia performances on youtube. in that recording, there were many more "I'ds" than on the cd ;)
