I think there has to be some "meat" involved with the prank to be a funny prank, just saying you got fired isn't much of a prank. I remember one year my Mom, who was not a jokester, gave me a phone message to call a Mr. Lyons, she said it was about something I lost. So, I call the number at her insistence, only to find out the phone number was for the local zoo, 30 or so years later I still think about that every April 1st.
Are you lioning about that. That was very catty of her. The PURRfect joke. I bet everyone was roaring over it. The mane thing is that you still laugh about it.
