Picard-Dorothy and Riker-Toto had been walking down the yellow brick road for about an hour or so when they came upon a cornfield. Picard stopped, remembering the story.
"What is it, Captain?" Riker-Toto asked.
"Let's see." Picard said cryptically.
They turned a corner and this time, Riker was the one who came to a halt.
"Geordi!" he cried.
"Commander?" Geordi asked.
"Hello," Picard said.
"Good that you came along, it was getting boring being stuck up on this pole."
Geordi was dressed in farmer's clothes with straw sticking out, and he was nailed up on a pole in the cornfield like a scarecrow. No, like The Scarecrow, Picard corrected himself.
"How can we get you down?" Picard asked, coming around him.
"There's a nail in the back. I'd have gotten myself down earlier, but I can't reach it."
Picard pulled up on the nail and the engineer sprawled on the ground, spilling straw everywhere.
"Are you all right?" Riker said, trotting over to him.
"Yeah, it's just this straw," Geordi said, picking some of it back up, "I can't move without it. " He laughed. "I would guess we're going to the Emerald City because you're Dorothy, and Commander Riker's Toto."
"Yes," Riker confirmed in a sad tone of voice, then updated him on events so far.
"Which means I'm the Scarecrow," he mused. The yellow brick road forked after the cornfield, reminding him of the movie-required watching in elementary school. "Should I tell you 'some people like to go both ways'?"
"No," Picard decided authoritatively. "We need to go the way where we will find the Tin Man. That way, we can continue the story."
"And get out of Q's home faster," Riker agreed. "Who do you think the Tin Man will be?" he asked.
"Well," Geordi said, pretending to be thoughtful. "Who do we know that's made of metal and wants a heart?"
They laughed, understanding, and took a left at the fork.
A/N Hope that's a good enough explanation for everyone knowing what Oz is.
