Well I can't tell jokes that good but I'll give it a try

This dude walks into a bar and sees a barrel in the corner so he goes to the bartender and asks ?? Why is that barrel sitting over there? the bartender says ??Go stick your dick in it and you??ll see why? so the dude sticks it in and then he goes back to the bartender and says ??That was great? and the bartender says ??You can do that every day of the week except tuesdays ?? the dude then asks ??Why? the bartender says ??Because it??s your turn in the barrel on tuesdays?
