“Why did the vegan cross the road?” (joke)

There have been several “vegan” versions of the classic “Why did the chicken cross the road?” joke. One version was printed in 2002 newspapers:
 
Q: Why did the vegan cross the road?
A: To save the chicken from Col. Sanders.
 
Another version was posted on Twitter on November 9, 2009:
 
“Why did the #vegan cross the road?Because she was protesting for the chicken, MAN! (Pump fist in air for emphasis)”
 
Another version was posted on Twitter by Kirker Butler on March 29, 2013:
 
Q: Why did the vegan cross the road?
A: To tell a complete stranger that he’s a vegan.
 
“How do you know if someone is a vegan?”/“Don’t worry, they’ll tell you” is a related joke to this last version.
