“I saw a hot dog vendor today…” (joke)

There is a difference between a “hot dog vendor” and a hot “dog vendor.” There’s a joke:
 
“I saw a hot dog vendor today… She was good looking, but I don’t really want a dog.”
 
The joke was posted on reddit (dad jokes) on April 27, 2016, and again on reddit on May 18, 2016.
