“Why didn’t the donkey cross the road?”/“Because he saw what happened to the zebra.”

“Why did the chicken cross the road?”/“To get to the other side” is a classic riddle from the 19th century. A chicken/donkey version is:
   
Q: Why didn’t the chicken/donkey a cross the road?
A: Because it saw what happened to the zebra.

 
The joke is that the chicken (or donkey) doesn’t want to be flattened, seemingly like a zebra at a “zebra crossing” (dark and light stripes on the street).
 
“RT @sickipedia: Why didn’t the Chicken cross the road?He saw what happened to the Zebra” was posted on Twitter by Varun Bubber (and others) on May 4, 2010. The joke originated on the Sickipedia website.

Wikipedia; Zebra crossing
A zebra crossing is a type of pedestrian crossing used in many places around the world. Its distinguishing feature is alternating dark and light stripes on the road surface, resembling the coat of a zebra. A zebra crossing typically gives priority to rights of way to pedestrians.
