“Strike the next question” (Texas lawyer joke)

A dumb lawyer, on the verge of asking a stupid question, interrupted himself and said: “Your Honor, I’d like to strike the next question.”
 
There’s nothing particularly Texan about this joke (on internet joke lists since at least 1996), but the joke always starts: “A Texas attorney…” Is it because those Texans down South are a bit stupid?
