Until the cows come home to roost

This beauty was overheard at a meeting. The speaker meant to say chickens but after the word “until” was uttered (uddered?) the vision of cows appeared in his head. This incongruent conflation is a mix of “until the cows come home” (for a very long time, forever) and “the chickens come home to roost” (one’s previous actions will eventually have consequences). Barnyard animals clearly are the culprits here. A big thanks to Jonathan Eliot for sending this one in!
