Two college students are riding on a New York subway when a tramp approaches them asking for spare change. The first adamantly rejects the man in disgust. The second, on the other hand, whips out his wallet, pulls out a couples of singles and gladly hands them over to the tramp with a smile. The tramp thanks him kindly and then continues on to the other passengers.
Outraged by his friend's act of generosity, the one student asks,
"What on earth did you do that for? "You know he's only going to buy something that isn't good for him with it."
The other student replies,
"And we weren't?"
