Not a joke ?

Once I was carrying a heavy bag on my shoulder to the class. My buddy stopped me and asked, ” Why the bag is heavy?” I replied, “There is a big cat in my bag,” in a funny way. He didn’t consider me, So I attempted to fool him so I opened my bag zip to frighten him that I am sincerely carrying a cat in my bag. As quickly as I opened my bag, a cat from my bag angrily jumped into my face. Thank God !!! my mom woke me up. – Sunny
