Hear No Evil, See No Evil, Speak no Evil, (Taste No Evil, Feel No Evil, Smell No Evil) Whatever sense you are using most at any given time, doesn't work. If you are listening to music you are suddenly deaf, if you are about to eat a big scoop of delicious ice cream you can't taste it, if you're looking for something you are suddenly blind etc. etc. etc.
How many suggestions can we make?
