The Perishers S01E20 - The Inch-thick Ketchup Sandwich

Marlon is working on an idea, he's inventing things. At the moment he is working on the Wheel. Maisie looks on in disgust. Then he shows off his latest invention, the Inch-thick Ketchup sandwich. Despite the warnings of Wellington, Marlon bites into it, squirting the ketchup all over Wellington. He goes off in search of Maisie and finds out to that she has been "shown" the invention as well. Marlon thinks it will revolutionise the fast food market, Wellington thinks it will revolutionise the dry cleaning market. Maisie says that Marlon should reinvent the bicycle and sits down on one of Marlon's failures, the Ketchup Cushion.
