Whackhead Simpson prank 

On 30 January 2009 Kyle was pranked on air by South African prankster Darren 'Whackhead' Simpson after Kyle made negative comments about Darren's jokes previously.  Should this be under "controversies" perhaps?  Although the prank was aimed at Kyle, it was actually his producer who was conned into thinking that Kyle would be interviewing Tom Cruise live.
