[NSFW] A guy walks into a bar (Warning, very long but VERY hilarious joke) It's my favorite one to tell.

He asks the bartender for a rum and coke and the bartender gives him an apple. The man is confused at first, but the bartender says "trust me, take a bite". The man takes a bite and proclaims, "Oh my god, this tastes like rum!" The bartender responds, "Now turn it around and take another bite." The man does this and to his surprise, it tastes just like coke. Bewildered, the man explains "This is amazing! This is now my favorite way to drink!"
Another man walks into the bar and orders a gin and tonic. Again, the bartender hands him an apple. "What the fuck is this?" says the new man in the bar. The first man ensures him by saying "Trust me, this bartender knows what he's doing." Hesitantly, the man takes a bite of the apple. "Wow! This tastes just like gin!" The bartender tells him to turn it around and take a bite. "Whoa! Tastes just like tonic! This is amazing!"
A third man walks into the bar. Before he can even order a drink, the two other men sitting at the bar say, "Hey this bartender has an apple for anything" "Yea! He has one for every flavor!" The third man responds, "Oh really? Any flavor?" He turns to the bartender and says, "Give me an apple that tastes like pussy." The men all laugh until the bartender takes out an apple and places it in front of him. Everyone watches as the man picks up the apple, slowly raises it to him mouth, and takes a bite. Immediately he spits it out and shouts "What the hell! That tastes like shit!" The bartender responds "Turn it around".
