I hope you’re not eating your dinner whilst reading this one (and if you are, what are you doing on the computer whilst eating anyway – you’ll get food in the keyboard).
Made from plastic and made to look, well, like sick (complete with “carrot chunks”) the idea is to shock and disgust adults by placing said item in a strategic place (e.g. in the middle of your Mum’s brand new living room carpet).
Sadly I’ve no fascinating tale related to fake “technicolour yawns” of my own to relate, but a great one is that told by Chunk to the Fratellis in The Goonies. He says about going to the cinema and making vomiting sounds before throwing some fake puke into the audience, which caused a mass vomiting session in the cinema. Funny, though perhaps not so funny had you been in the audience in question!
So if the inner child inside of you still feels like playing a practical joke of this manner (perhaps your Mum has just had another new carpet fitted and it would be a good repeat gag?) you can get hold of your very own plastic sick from Silly Jokes.
