Sims 3 - Prank on colleague

It's been quite sometime since i have been able to play sims 3. By now, almost all have completed their lifetime wish except Dephinia and the new 2 generation. Kalzoky, was able to complete his wish at the elder stage. And i went on testing , noticing that John Wakefield can actually play prank on his colleague.

By clicking on the tower building, i can assign him to setup prank. HOwever it seem that His prank turn out to be failure. Nevertheless everyone have a good laugh and i guess this is still a good outcome :)
