Hahaha, but nah, this was in South Yorkshire, not East Yorkshire. They're dee-dars down there - "Er nerrr" is generally a Hull accent :)

In Hull they would have said "Err nerr, there's a rerbert on me fern curl!" (Oh no, there's a robot on my phone call).

In Rotheram, they'd just sound like either Sean Bean, or Sean Bean with a higher pitched voice.
