Telephone Poles

Two telephone company crews were putting up telephone poles. At the end
of the day, the company foreman asked the first crew how many poles they
had put in the ground. “Fifteen” was the answer.
“Not bad, not bad at all,” the foreman said.
Turning to the blonde crew he asked how many they had put in. “Four” was
the answer.
“Four?” the foreman yelled. “The others did fifteen, and you only did four?”
“Yes,” replied the leader of the blonde group, “But go look at how much they
left sticking out of the ground.”
