There's one boy in our finance team and he's just plain weird. Since he has started he has claimed

+ Amazon were not delivered presents for Christmas, you have to wait until January 1st for all of them to be delivered. This was in November.
+ Amy Winehouse has a lookalike. When she needs to meet her manager or perform a really good gig, she sends along her lookalikey and everything is fine. I remarked 'why don't they just use the lookalikey all the time' and I got ignored.
+ I said I was going to set up a gift wrapping service, £1 with bows, ribbons and everything colour co-ordinated. I was joking. He's gone and set his own for 50p, so he can under-cut me. He's deadly serious.
+ We're all going out for lunch today and I joked about no sweeties before we eat, so now he's eating really loudly and making eye contact with me.

Can I kill him? Also he writes really untidy.
