About 2 furlongs. Not to be confused with a bees dick.

No matter how many times I measure, I get 300 dicks. I think there's something wrong with my wood.

That right there is quiet evidence of why trucks happen to small men.

I gopher’d a fair bit of construction and was always given “a blonde one” as a unit of measurement.

Never dicks, but construction workers in my experience make assumptions about dick measurements so I suppose that’s why I never heard it.
