A hobo walks into a bar...

A hobo walks into a bar. The barman shouts at him 'Get out! We don't serve your type in here!' The hobo says 'OK OK I'll leave. But all I want is a toothpick'. The barman, suspicious, hands him a toothpick and the hobo leaves. 5mins later another hobo comes in and the barman says 'get out! We don't serve your type in here' The hobo says he will leave but asks for a toothpick first. The barman hands him one and he leaves. Over the next few minutes, several more hobos come in and ask for toothpicks. The barman is really confused. He decides the next time one comes in he'll ask him what's going on. Couple minutes later one comes in and says 'can I have a...' The barman says 'I know I know you want a toothpick'. The hobo says 'actually I want a straw'. The barman says he'll give him one but first he has to explain why all these hobos have come in and asked for a toothpick and now he wanted a straw. The hobo explains: 'somebody has been sick outside. But all the best bits are gone....'
