For example:
Duck
Tuck
Truck
Track
Trace
Race
So it's like an infinite round of that. There are rules:
1: Each word has to be real.
2: You may do ONLY one operation at a time. Operations include changing one letter, adding one letter, or subtracting one letter. You may not rearrange letters.
3: No horrid language. I know how tempting it is to post directly after "duck"...Just please refrain from it.
At any rate, I'll start!
