Mushrooms!
"Hey, Buck. What kind of mushroom do you think this is?"
"Um, I dunno, Steve, why?"
"I was thinking, you know, Alice in Wonderland.... Maybe just a nibble..."
"Steve, no!"
"But we're supersoldiers! What could go wrong?"
"Steve! Now we're in some kind of mushroom kingdom!"
"Come on, Buck! You were just saying how you wanted to see alien landscapes."
"Steve, pal, this is getting to be a little overwhelming."
"It's so beautiful!"
"You are completely out of your head right now."
"Yes, I am!"
"Wow! Thank goodness we made it back to terra firma!"
"Bucky, you know what? It's just so good to be alive!"
"I can't even argue with that."
