Looks for a file in the load path with the name methodname.dat, reads the lines from that file, then gives you a random line from that file. Raises an error if it can’t find the file. For example, given a file named “horse.dat” in your load path: >> Random.horse

> “Stallion”

>> Random.horse

> “Pony”

>> Random.horse

> “Mare”

>> Random.horse

> “Clydesdale”

>> Random.horse

> “Stallion”

>> Random.horse

> “Mare”
