Though it tends to dull the effectiveness of a semi-obscure reference when you feel the need to explain it, I will do so for the sake of the young uns in the crowd:
LaGrange, TX is the site of the infamous Chicken Ranch. Basically, its your top-of-the-line old west whore house.
"Best Little Whorehouse in Texas" was a movie with Dolly Parton about the chicken Ranch.
texaslonghorn and TEXASAGGIE players reportedly got freeebes before the big game back in the day. Or maybe winner got freebes? can't recall.
And, 70's-80's blues-rock band ZZTOP wrote a song in the mid 70's called LaGrange with the above quoted lyric. (you've seen ZZTop, right? the dudes with the long beards down to their belly buttons? "She's got Legs, she knows how to move them, she never begs.....")
and now you know.... the rest of the story.
who says HD isnt educational?
