That's either crazy toilet paper or the biggest sheet of LSD I've ever seen!!!!
Blue heard a turkey. Pink heard a duck. In truth, it was a duck. Blue insisted it was a turkey and was frustrated by Pink's inability to hear the non-existent turkey. Blue pressed the issue, raising stakes until they split up. Eventually, Blue realized it was a duck and admitted his mistake, and hooray, they were back together again (and maybe had good make-up sex - I'm not sure if that was implied or not, but the sun [God?] seemed to enjoy watching it, either way).
Down here on Earth, it's clear Blue and Pink have complex underlying issues, likely irreconcilable, and that this truce is temporary until the next little thing's blown out of proportion. That or Blue's crazy. Either way, the police will probably wind up frequenting the domicile for domestic assault. Blue at least has a temper.
-Or maybe there was no duck.
