Former Australian Special Forces Commando Wes Hennessey says he thinks it’s “fabulous” that Prince William has a sense of humour. 

Prince William cracked a ‘dad joke’ during his surprise visit to a school after a student wrote a letter to him about mental health.  

The boy wanted to showcase the work the school was doing for mental health.  

“I think it’s fabulous that he has that sense of humour,” Mr Hennessey told Sky News host Erin Molan. 

“That’s commendable.”
