Best "Dad" joke

[Raider4]

I once hired a limo but when it arrived, the guy driving it walked off!

I said "Excuse me? Are you not going to drive me?"

The guy told me that the price didn't include a driver...

... so I'd spent £400 on a limo and have nothing to chauffeur it!

Or...

"What was a War like, Dad?"
"Eh? What? ... Oh! The 'WAR' !"
