Christmas cracker crap

As I was clearing out some stuff, I came across a load of Christmas crackers. Naturally we pulled them, and got the following prizes. No jokes though, so I will include a joke I think is appropriate for each prize

1. Fake lips that make a weird whizzing sound when you blow them

Joke - Why did the dinosaur cross the road? Because chickens hadn't been invented yet

2. An ace jumping frog that doesn't jump so much as hurl itself into the nearest wall

Joke - Why couldn't the pirate play cards? because he was sitting on the deck

3. Nit combs

Joke - How do you make a Swiss roll? Push him down a hill

4. One fake fingernail that serves absolutely no purpose whatsoever

Joke - When is a door not a door? When it's ajar
