You can’t miss it
Two Englishmen were in New York for a visit. One morning they went out to look for a famous church, but they didn’t know how to get there. They stopped a man and asked, “Excuse me, can you tell us the way to the North Church?”
“Go three blocks and turn left,” he said. “You can’t miss it.”
So the Englishmen walked three blocks and turned left, but they didn’t see any church. Then they asked a second man.
“Excuse me, but we’re trying to find the North Church.”
This one said, “Go three blocks and turn left.” But again they couldn’t find the church. In the end they asked a third man, “Excuse me, how can we get to the North Church?”
“Go three blocks and turn left. You can’t miss it ”
They walked three blocks and turned left for a third time. This time they found the church.
“Is everything in New York three blocks and a left turn away?” they asked themselves.
Just then a man walked over to them. “Excuse me,” the man said “Where is the East Park? Can you tell me?”
“Go three blocks and turn left,” one of the Englishmen said. “You can’t miss it.”
