In for a penny, in for a pound. Here's one I submitted about the Greek robbers who escaped from prison twice in 3 months - in a helicopter.
GUARD: Welcome to Athens prison. The most secure prison in the world. For you the crime is over. Escape is impossible.
PRISONER:They have not built the prison that can hold me.
GUARD: You reckon without our state of the art security systems. We have sniffer dogs which can detect the merest hint of metal in a cake.
F/X:A GROWLING DOG AND THE CLATTER OF A PLATE HITTING THE FLOOR
GUARD: That giant baklava your mother brought in seems to have aroused his suspicion. Eat Stavros, eat! <BEAT> Ah-ha! Just as I suspected a giant file.
F/X:A DOG SCOFFING FOOD NOISILY FOLLOWED BY A CLANG AND A YELP
PRISONER:Curse you Stavros! Baklava is a pastry not a cake, I was sure you would be fooled.
GUARD: No sweetmeat or sugary comestible containing escape paraphernalia gets past Stavros! <BEAT> And tunnelling is impossible, all our cutlery is made of a special metal which melts if it comes into contact with soil.
PRISONERamn!
GUARD: Our vaulting horse contains no hiding place, and the open trucks of hay which unaccountably enter and leave the prison on a regular basis are so precisely weighed that if a driver gets in after stepping in one of Stavros' poos it would trip an alarm.
PRISONER: I'm not surprised. They stink.
GUARD: It's not his fault. It's the cake. It plays havoc with his metabolism. <BEAT> Now, do you have any questions before I slam shut the door of your cell and leave you to brood on the impossibility of escape?
PRISONER:Just one. I suppose you have an impregnable storage place for the prison's supply of aviation fuel?
GUARD: Of course, do you think we are amateurs? It is stored on this very floor, protected by a flimsy lock and our oldest and least competent guard.
PRISONER: Well, you seem to have thought of everything. Damn you!
GUARD: Indeed. Prepare yourself for a long and hopeless stay.
F/XOUND OF SOMEONE BUMPING THEIR HEAD ON SOMETHING METALLIC.
GUARD: Ow! Do you have to have this thing in here?
PRISONER: Sorry officer, it's my life-size helicopter nightlight, I can' sleep without it.
GUARD: It's a health and safety hazard, see that it's gone by morning
PRISONER: No problem.
