Hokey humor (4)
I believe the answer is:
corn
'hokey humor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for corn that I've seen before include "Hard thickening of the skin on a toe" , "Grain; hard skin" , "Cereal; grain" , "Something unoriginal - cereal plant" , "often seen in ears" .)
