Laugh when he goes into the stand (2-3)
I believe the answer is:
te-hee
'laugh' is the definition.
(I've seen this before)
'he goes into the stand' is the wordplay.
'goes into' is an insertion indicator.
'the stand' becomes 'tee' (I've seen this in other clues).
'he' put inside 'tee' is 'TE-HEE'.
'when' is the link.
(Other definitions for te-hee that I've seen before include "Laugh" , "chuckle" , "That was a joke!" , "Mocking exclamation of laughter" .)
