A disgusting joke

One day a homeless man runs into a pub and shouts “a fork! A fork! Has anyone got a fork?!”. He grabs a fork off the floor and runs out of the pub. No soon as the homeless man has run out another homeless man runs in and shouts “please a fork, a fork, has anyone got a fork?”. He steals a fork from someone’s table and runs out of the pub. Not 10 seconds pass until another homeless man runs into the pub and says “ a straw, a straw, I need a straw!” The barman, now irate with the situation, demands to know what’s going on with all these forks and straws. The tramp turns to the barman and says “someone’s been sick outside and all the good bits are gone”.
