Two homeless guys walking down the street. Homeless Joe says to homeless Bob: "Bob I'm the luckiest hobo ever! Yesterday I found $20 on the ground, bought myself a box of wine and I've been drinking like a king!". Homeless Bob retorts: "I can one up you Joe. I'm the luckiest hobo ever because yesterday I found a woman tied up by the train tracks. I rescued her and we went back to my box and have been f*cking all night!".
Homeless Joe: "wow that is way luckier than me! But does she give good head?".
Homeless Bob: "I'm not sure. I haven't found it yet."
