I used to wonder how the BBC could get away with showing that show to kids.
The characters' names made it so obvious, but the pun seemed to go over broadcasting bosses heads at the time.
I thought it was a hilarious show.

I am reminded of the stunt pulled on the RTÉ TV (Network 2) show 'Dempsey's Den', by 'Zig and Zag' (two alien hand puppets with an increasing sense of the zany).
Zog asked Zig to "show all the children how to do an impersonation of a pig"
Zig 'looked' at Zog for a moment and went off screen left.

After a pregnant pause Zig came back on screen with a miniature RUC uniform, complete with peaked cap and sunglasses, put on his best NOI accent and shouted into the face of Zog:
"Get out of that car, you!!!"

Camera panned back to a 'brave looking' Ian Dempsey, as he told the 'all the kids' (but in reality was pleading with his producer), "We'll be back after this short break"
