Succeed with information technology? Don't make me laugh (4,3,2)
I believe the answer is:
come off it
'don't make me laugh' is the definition.
(I've seen this before)
'succeed with information technology?' is the wordplay.
'succeed' becomes 'come off' (I've seen this before).
'with' says to put letters next to each other.
'information technology?' becomes 'IT' (common abbreviation).
'comeoff'+'it'='COME OFF IT!'
(Other definitions for come off it that I've seen before include "How to stop sex addiction?" , "that's most unlikely" , "You're mad!" , "get down from there" , "Don't talk rubbish" .)
