Crack band with no name (3)
I believe the answer is:
gag
This could be a double definition.
'crack' is the first definition.
(both can mean a joke)
'band with no name' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for gag that I've seen before include "Funny" , "Prevent from speaking freely" , "Make quiet" , "Joke (colloq.)" , "that renders one speechless" .)
