Two Sardars and their Horses

 Then there were two sardars, Zail singh & Jarnail singh.
 Both of them bought a horse each.
 
 "How will we know which
 is your & which is mine?" asked Zail.
 
 "Easy"replied Jarnail.
 "I'll cut mine's tail,yours will be the one with tail"

 This was heard by a few boys ,they cut the other's tail too.

 Next morning the confusion continued.
 "Don't worry "retorted Jarnail. 
 "I'll tie a bell around its neck, yours will be the one without
  the bell."

 The boys heard this also & cut the bell.

 The next day, Zail got frustrated & said 
 
 "Okay now the last criterion,
 white will be yours & black will be mine."
