Captain's Log, Stardate 44673.6. The USS Enterprise has encountered yet another giant swirly thing in space, threatening a small Federation colony with being swirled.
"Well, let's get to work, we bounce something off the Deflector Dish and the swirl goes away as usual."
"Captain, there is a problem. The swirly thing appears to be composed of particles that closely resemble lignin."
"Why does this present a problem, Mr Data?"
"Well, Sir, as you know, lignin is, in layman's terms, wood."
"You mean..."
"Yes, Captain. The Deflector Dish does not do wood."
"Really?"
"Yes."
"You sure?"
"Yes."
"...Tits."
