"Gentlemen... behold!" Professor E. Gadd exclaimed while showcasing a device that turned the magma of the Grumble Volcano into different colored beans. "These can be harvested into coffee beans for you to make coffee with! Doesn't that seem exciting?"
"Great Scott!" Doc Brown exclaimed in disbelief for he was there to fuel up his DeLorean time machine with him not approving of this weird science. "Do you have any idea what you are messing with in tinkering with the volcano's natural products?"
Elvin Gadd simply laughed while he adjusted his glasses. "Perhaps but I don't frankly mind. It's actually pretty interesting-"
The volcano then sent a big ball of fire right at the machine and caused it to blow up, with Doc Brown trying not to chuckle while E. Gadd was left in disbelief.
