Explosion at the Bruce cottage

I decided to fix the last two eggs for breakfast this morning.  So I took out a heavy, deep, ceramic cereal bowl, sprayed it with non-stick spray, and cracked and dropped in the two eggs.  I covered it with a damp paper towel so I wouldn't have egg to clean up inside the microwave.  Zap for 1 minute.  Took a peek, then zapped for another minute.  I carefully removed the bowl (very hot).  Hmm. A slice of cheese would taste good on that, so I took the package out of the frig and removed a slice and placed it on the eggs, hoping it would melt.  It just sat there.  So I walked to the opposite side and took out a fork and knife. When I poked my wonderful egg/cheese meal with the fork it exploded.  And I mean, everywhere, including my nice light teal shirt that matches my teal and yellow summer slacks and all around the coffee pot and microwave.  Plus the steam scalded my right forearm. So, it wasn't cooling while I did those other tasks, it was building up steam.  There's a message here, and I'll figure it out.
