My pranks backfire. Once I gave my son condoms as a gag gift; his excitement and declaration that he really needed them definately made the joke on me.

My daughter at one time had my only grandkids so she enjoyed an elevated status. My son, daughter in law and myself cooked up a plan to convince my daughter they were having a baby. We all expected her to be unhappy about it. Nope she was so damn happy and excited that her baby brother was gonna have a baby that she cried.

So we felt like assholes.

The only "prank" that ever succeeded was when I heard someone was gonna egg me from their car so I hid in my boat and threw spoiled eggs in their car when they pulled up
