 I'd been trying to find a good job ever since graduating college. It turns out that studying military history of Liechtenstein is n't the sort of thing that most employers are interested in, and I'd been bouncing from temp job to temp job for the last year. This particular advertisement was actually in the classified section of the newspaper, right next to the crossword puzzle I was solving to pass the morning away. It caught my eye as I was puzzling over 14 across. I'd always had a vague interest in bartending, and since I had time to spare and the address was three blocks away I thought I'd drop by and ask. 
 
 I nearly walked past the bar entirely. I only noticed it because a rather unkempt man sitting on the curb outside fishing in a puddle asked me if I could buy him a drink ( I do n't live in a great part of town -- you do n't make much money on temp work ) and gestured towards the entrance. I carefully ignored the man and pushed open the door into the bar. The inside was a lot more spacious than I would have expected from the entrance, and was rather nicer-looking than most bars in the area. I wondered why I'd never heard of the place before. It was pretty quiet, which I guess was to be expected at 10 in the morning. 
 
 As I stood near the door, the bartender came through a door from the back room and stated to nobody in particular, `` We do n't serve time travelers here.'' Slightly confused, I approached the counter. As I walked up, he gave me a harried look and asked, `` What are *you* here for?'' 
 
 `` Um... there was an ad in the paper for a bartender...'' I replied. 
 
 `` Oh, right.'' he said, looking relieved. `` Knock knock.'' 
 
 `` Um, who's there?'' 
 
 `` Heifer.'' 
 
 `` Heifer who?'' 
 
 `` Heifer cow is better than none!'' 
 
 Despite how terrible the pun was, I could n't help bursting out into laughter. 
 
 `` Oh good,'' he said, `` you *do* have a sense of humour. The last applicant did n't understand it when Tom Swift told him there was too much vermouth in the martini. When can you start?'' 
 
 `` Do n't you want to test me on making drinks first?'' I asked. 
 
 `` Oh, that's not important,'' he answered. `` Most of our customers are n't here for the drinks anyway.'' 
 
 `` What?'' I asked `` How do you make money then?'' 
 
 `` Did n't you see the name of the pub? It's the *Deja Brew*. We're famous for hosting all of the world's bar jokes. We're booked solid for six months out, and we have more rabbis and priests come in than any other bar in the city.'' 
 
 I was more confused than ever. `` You *host* bar jokes?'' I asked, incredulous. 
 
 `` Well, where did you *think* they took place? Here, of course! Are you interested in the job, or not? I have a contingent of mathematicians coming in this morning and I need to get ready for them.'' 
 
 It certainly seemed more interesting than temp work. `` I'm in. When can I start?'' 
 
 `` Right now! According to the schedule an infinite number of mathematicians are due to arrive any minute now. They'll only need two beers, but I'm sure we'll need crowd control.''
