in aleing health

What you will eventually be if you regularly "toss back tall frothies" at da pub.

In da music video, "Prop Me Up Beside The Jukebox If I Die", singer Joe Diffie naively treats da motionless-and-unresponsive bar-patron as if he's merely in aleing health ("It's closing time, Buddy --- you don't hafta go home, but you can't stay here."), not realizing dat he's actually a deceased corpse who's been brought there for his "final hurrah" in da raucous live-and-recorded-music-offering-and-liquor-serving-establishment-hopping lifestyle.
