This all reminds me of something I heard an ex-military friend say to his wife once, they were talking about sleeping on the ground:
Him: I ain't ever sleeping 'on the ground' again.
Her (making fun of him): Well I thought you was a Green Beret
[which he was] that slept on the ground all over Vietnam!?
Him: Well, there was million NVA trying to kill my ass, then...
...and I ain't doing
that shit no more, either.
