Motorcycle - Merlin
"Merlin," Arthur said in exasperation, "what are you doing? What is that thing?"
"It's a motorcycle," Merlin said.
"A what?"
"A motorcycle."
Arthur looked at the strange contraption.
"What does it do?" he asked.
"I'm not sure," Merlin said, looking at it appraisingly. "I haven't decided."
"Oh," said Arthur.
"I think you're supposed to sit on it."
"Sit on it?"
"Yes."
Arthur looked at it suspiciously, but finally gave in and sat on it. Merlin sat on it as well. Merlin concentrated, and with a growl, the engine came to life. They started to go along the track, faster and faster, until they finally crashed headfirst into a tree.
"Merlin," Arthur said when he finally regained consciousness, "next time you decide to make something like that, test it first.
Merlin grinned. "That was fun!" he said.
Arthur rolled his eyes.
