One day a group of penguins were waddling past Santa’s workshop. Santa was tinkering away at a new toy invention, trying to curb the current elf enthusiasm for platinum. His new invention was a bicycle that trailed with fog; the faster a child could pedal, the more fog the bicycle created. Santa looked up from his workbench as he heard the group of penguins saying:
"And if you ever saw him…" said one.
"You would even say it GLOWS!" said another.
"Like a light bulb?" asked the last.
"Like a light bulb!" replied the first two.
