I know the exact spot this is from years ago. Its just north of a little town called Lindale (North of Tyler, south of Mineola).
Dudes hallopinos were actually pretty legit. He also had the sign misspelled so poorly because it “gets people’s attention and makes em laugh”.
I used to spend a lot of time in this area (years and years ago) and the guy did indeed write it up to grab people’s attention.
