Barb Needs Glasses

Barb was confused because she tried to put her coffee in the microwave to warm it up without getting her glasses.  She wanted to heat her cup for 2 minutes 22 seconds.  She pressed the numbers correctly but she pressed delay instead of start.  Then she hit 2 minutes and 22 seconds again and pressed start.  The microwave ran for 4 minutes and 44 seconds.  The coffee boiled over and burned on to the microwave.
