The Diplodocus, the Unicorn and the Pterodactyl!

Train journey to London. Shimmey, Dribbles and Trilobite amuse themselves by telling the story of a diplodocus called "Di-plod-o-cus"

Shimmey (in the style of a nature programme presenter); The diplodocus is in the Savanah.
Trilobite (in a dopey, slow, dinosaur type voice); "I'm in the Savanah"
Sh; The diplodocus does not live in the Savannah, he is lost.
Tr; "I am lost"
Sh; There is not much food in the Savannah so the diplodocus is forced to eat sand
Tr; "It helps aid my digestion"

The story progresses such that the diplodocus has a tshirt with a geeky logo on and a tool belt to hold his welder. He also has a laptop on which he checks facebook, but has trouble with due to his massive feet.

Sh; In the distance you can observe the pterodactyl. He is having a tea party...
Dribbles; with a unicorn!
Sh; The pterodactyl and the unicorn are having a tea party. The diplodocus was not invited.
Tr; "I was not invited. This makes me sad"
Sh; The diplodocus is very sad, he tracks the party on facebook
Tr; "They look like they're having so much fun"
