If you need help, why don't you ask Dave?

I kept going up to these guys on the platform asking 'Dave?'

If you want to know why, ask Dave.

If I asked Dave for a ban on double entendre, would he give me one?

He had meant to ask Dave if he liked living in Derry.

Edie asks Dave what the biggest difference is between being married to her and to his first wife.

They'd ask her a question, and she'd write it down and then ask Dave.

I asked Dave what it was about, but he wouldn't tell me anything else.

I decided to get a pair of snowshoes, and I asked Dave what to buy.

Are you going to ask Dave where he's been?
