I always say that if a cartoon gag idea works, it can be described, you don't have to draw it.
I'm going to describe a couple here and you lot can tell me if they work.
There's another angle to this, if you can bear it. Sometimes, one idea kicks you off in a similar direction, so I've written two versions of the same joke, and a third version which slingshotted off the first two. The second version requires you to know that Crocodile Dundee is played by Paul Hogan.
1) A cat and a dog are canoodling in bed together. The cat's husband, obviously just home from work, surprises them. He glares at his wife and says: "is that all you can say - 'miaow'"?
2a) An iconic Aussie bushman is sitting at a dinner table. He holds up an outsize, odd-looking utensil. A speech balloon above his head has him saying: "Nah, that's not a spork. THAT'S a spork"
The strapline reads; 'This was the last time Marie would ask Crocodile Dundee to her mother's.'
2b) An ageing comedy actor is sitting at a table alongside a drunk lady who is saying "That's not a spoon, THAT's a spoon".
The strapline reads "Paul Hogan was getting tired of his public"
2c) A doctor and his patient, a revered Shakespearean actor lately reduced to taking a part in Lord Of The Rings, sit across from each other. The doctor is declaiming theatrically "It shall not pass!"
The strapline is: "Sir Ian McKellan failed to see why his constipation was a source of amusement."
3) A workman has pulled a cupboard away from the wall to reveal a huge hole behind it. He is saying to the householder (a woman) "this is where they're getting in".
The strapline reads: "Mrs Thewlis was shocked to find she had rhinos"
That'll do for now.
