Who spiked the punch?

It wasn't until today that those jokes about "who spiked the punch?" finally make sense to me!

At the office today the sales team hosted a casual potluck buffet luncheon to get us in the holiday spirit. At which there was a punch bowl...

And after only one glass - I feel a little, um... peculiar... Which leaves me asking only one question:

Who spiked the punch? :)

PS. I was planning on doing some work this afternoon, but I think it's probably in the company's best interest that I do not. I heard that the customer service team is having a little gathering of their own. Perhaps I'll head down the hall to check that out. Maybe they'll have punch too...
