A flat joke

Tara was woken up by loud raps on her knocker,

Ben had been hurt at work,he was a Liverpool docker.

She arrived at the hospital in a flurry,

Ben was precious to her,she was full of worry.

She asked the receptionist at which ward she would find poor Ben,

"Ah yes he was knocked down by a steamroller,he's in ward 7,8,9 and ten."
