How's about 'When it comes to puns you're not much Cop, Land yourself looking a right twat if you keep trying?'
Already done the Cliffhanger one. If it hadn't already been used I'd have said that your effort would be Judged Dreddful. Goes to show that not everyone is a Specialist.
Yes you can pop but as I was in the middle of editing my previous response it would appear a tad unfair as I led you down the garden path and you might have been Driven to it.
Even by your 'in you pop' standards this is well below par. Robocop? Seriously? Deserves a Bullet To The Head.
Stallone puns you f*cknuckle. Although saying that I checked out his output over the years and he's not what you'd call prolific. Mostly knocks out one a year so not many Sly puns to be had.
