My Mate Jimmy

It was 7:30am on a wet Sunday morning and the party was still in full swing as I waited outside a town centre house for my fare. After a minute or two a guy dashed out and opened the cab door and thrust some cash into my hand. "Your fares coming out" he said "do us a favour and pretend you know him, it's just a windup." Being a lover of a good windup I more than willingly agreed. He then quickly told me the guys name and address and a few more handy facts about him. Moments later my fare, who looked as if he had just woken up after spending the night in a hedge, staggered out.
 As soon as he got in the car I greeted him with "Hi Jimmy are you going home then mate?" He looked at me quizzically and nodded and after a minute or two asked "do you know me ". I gave him my best hurt expression and replied" Yes course I do, hey! You're not mad with me for not making your birthday bash last week are you?" "Err no mate" he replied and then kept giving me sideways glances as I asked him "how his sister Marie was doing" and" was he still seeing that skinny lass." When we reached his street he asked stunned "do you know where I live as well?" "Of course I do" I said as we pulled up outside his house. Bewildered he started to look in his pockets, for cash to pay me "no Jimmy have that one on me" I said. "Thanks mate" he said sorry for not recognising you, I think the drink is getting to me" "What do you mean?" I asked "loads of people were talking to me last night and I couldn't remember who they were" he said. As he walked away I could hear him muttering to himself about "not touching that stuff again" and "never going out again."
