Why do birds fly south for the winter? Because it's too far to walk. What do you call a bright, sunny day that comes after two cold, cloudy days? Monday. A snake slithers into a bar. The barman says, "I can't serve you, you obviously can't hold your drink." Which side of a chicken has the most feathers? The outside. Two parrots on a perch. One says, "Do you smell fish?" An eel slithers into a bar. The barman says, "I can't serve you, you're legless."
