An Old Family Secret

A man is driving down a country road when his car breaks down. He gets out and walks about a mile until he finds a driveway. He follows the driveway up to a farmhouse. On the porch was an old farmer lounging in his rocking chair. He says to the man, "Well, how you doing son?"
The man says, "Sorry to bother you, but my car broke down. I was wondering if I could use your phone to call for a ride."
Farmer says, "Sure thing. Head right in and make yourself at home."
The man heads in and calls for a ride. As he comes back out to the porch he turns to the farmer and says, "I noticed you have some milkweed at the end of your driveway. If you give me a jar, I will go over and come back with some milk."
The farmer says, "You're crazy boy! You cant get milk from a milkweed!"
The man says, "It's an old family secret. If you give me a jar I will come back with some milk."
The farmer complies and he heads over to the end of the driveway. Sure enough he comes back to the farmer with a jar full of milk. The farmer yells, "How in the heck did you do that boy!?!"
He replies, "It's an old family secret."
The farmer says, "I like you son. You come back anytime."
The man leaves. A couple weeks pass and the man finds himself on the same road. He decides to pay the farmer another visit. He arrives at the farmhouse to find the farmer lounging in the same rocking chair. The farmer says, "I remember you! How you doing son?"
The man says, "I'm good. I noticed you have some honeysuckle at end of the driveway. If you give me a jar, I will come back with honey."
The farmer again cries, "You're crazy boy! You can't get honey from a honeysuckle!"
The man says, "It's an old family secret."
The farmer gives him a jar again and he goes to the end of the driveway. Sure enough he comes back with a jar full of honey.
The farmer screams, "How did you do that boy!?!?"
The man replies, "It's an old family secret."
The farmer says to him, "You can come back anytime."
A few more weeks pass and the man decides to pay the farmer a visit again. He pulls up to the farmhouse and sees the farmer lounging in the same rocking chair. The farmer says, "Well, its good to see you. How you doing son?"
The man replies, "I'm good. So I noticed at the end of your driveway you have some pussy willow. If you.."
The farmer interrupts the man, "Hold on. I'm coming with you for this one!"
