“What were the Aggie’s last words?” / “Hey y’all, watch this!”(joke)

A common joke has it that a Southerner/Redneck/Aggie/Texan utters these famous last words:“Hey y’all, watch this!” (Or, “Hold my beer and watch this!”)The implication is that the none-too-bright show-off does something stupid that costs his or her life.
 
The joke has been cited in print since at least 1995 and has been told frequently by redneck comedian Jeff Foxworthy. Texas author Kinky Friedman has also frequently use the joke, and the joke often is told about a Texan or a Texas A&M Aggie.
