I made a sponge cake for my Managers bithhday at work out of a REAL sponge. Our whole engineering department knew about it so everyone crammed into his office to watch him cut his cake that wouldnt cut . The knife just sprung off the sponge.

I had also made a real cake & brought it in after he figured out there was really something wrong with the cake (or my baking) everyone got a laugh at how hard & long he kept trying to cut it.

My other good one was withvanother group manager. He asked me to keep his pothos plant watered whike he was on vacation. No problem till I got sick but while at home I trimmed back my own pothos plant & let the trimmings die. I put the dead cuttings in a pot that looked just like his. I got back before he came back from vacation & replaced his beautiful thriving pothos with the dead cuttings pot. He was so upset that his plant had died while he was away. I let him think it was dead until the very end of the day when I finally brought back in his beautiful thriving pothos plant. I never did live down the name "plant killer"though.
