That bus has sailed

On the New Rules segment of Real Time with Bill Maher on HBO, Maher is talking about the need to return civility to political discourse, but then said “that bus has sailed.” This is a congruent conflation of “that ship has sailed” and “that train/bus has left the station”, both meaning the act has already been done. This is similar to an earlier post, “that train has sailed”, uttered by Austin Powers in the movie Austin Powers, International Man of Mystery, when he was speaking to a drunk Vanessa:

She was very groovy.
Your dad loved her very much.
If there was one other cat in this world that could have loved her and treated her as well as your dad then it was me.
But unfortunately for yours truly that train has sailed.
Vanessa?
Vanessa? Hello?

A big thanks to Harold Jackson and Paula Garrety, both who heard this one and passed it on.
