Comedy Central chump tours (6)
I believe the answer is:
humour
'comedy' is the definition.
'central chump tours' is the wordplay.
'central' means to look at the middle letters.
'tours' becomes 'our' (I am not sure about this - if you are sure you should believe this answer much more).
The middle letters of 'chump' are 'hum'.
'hum'+'our'='HUMOUR'
Can you help me to learn more?
(Other definitions for humour that I've seen before include "Mood or something funny" , "gags?" , "Gratify by compliance" , "Bodily fluid" , "Quality of funniness" .)
