Why did the turkey cross the road twice?
To prove he wasn’t a chicken!
The Turkey's Double Crossing
Explanation
The humor comes from the unexpected reason a turkey crosses the road twice. Instead of a practical reason, it's to prove he's not a chicken, playing on the stereotype that chickens cross the road and the common phrase 'chicken' meaning 'coward'.
