Tour leader being listened to and laughed at (5)
I believe the answer is:
guyed
'laughed at' is the definition.
('guy' can be a synonym of 'laugh at')
'tour leader being listened to' is the wordplay.
'tour leader' becomes 'guide' (I've seen this in another clue).
'being listened to' indicates a 'sounds like' (homophone) clue.
'guide' sounds like 'GUYED'.
'and' acts as a link.
(Other definitions for guyed that I've seen before include "Secured with rope" , "sent up" , "Made fun of - kept in position by ropes" .)
