A doctor and a truck driver...
A doctor and a truck driver are both in love with a very beautiful woman named Sara and the competition is fierce. Right as the truck driver is starting to get in good with her, his company sends him on a week long job, but before he leaves he brings Sara 7 apples. 

She says "It's perfect! 7 is my favorite number and apples are my favorite fruit, how did you know?" 
Being an honest man, he replies "I didn't."

"Why would you give them to me then" she asks confused. 
"Because an apple a day keeps the doctor away"
