Herbert Nehrlich - Puzzling, Ain't It

For those whose observation powers
were washed away in last year's showers
I say perhaps your ears are too
sealed tightly with some funny glue.
How many senses do you use
or are they numbed by tasty booze?
The secret will not be let out
says this (quite disappointed) Kraut.
