Won singular sensation?

I just don't get this. First of all, I would never have expected Jim to be a joke leader (his usual style is to repeat someone else's joke immediately after they've said it all the while laughing). But, after his debut of the whole Won & Theiu sound like one & two joke a couple weeks ago the joke has developed into an entire genre of Won & Theiu sound like one & two jokes that everyone (save me, it seems like) finds hilarious. Seriously, every afternoon for a while now I've had to listen to a whole repertoir of "we have to pick up Won but not Theiu", or "we have Theiu but no Won".

The arc of this "joke" typically starts out with a discussion of who was on the van on any given morning and who we still have to pick up (since we have to make special trips to pick up both Won & Theiu at their individual stops). Then, typically Jim or Fred will make the "Won but not Theiu" or "both Won & Theiu but not three or four". Finally, Fred will leave the number comparison behind will usually resort to a really bad play on words, like "I think we should listen to some Theiuns" or "I wont (prounced like want or the name Won plus t sound) some air conditioning".

I just don't get these jokes. I mean I get them, their names are hominyms for one and two (and to and too). But, I don't really get why everyone seems to find them so funny. I, frankly, find them irritating, which is weird because I love both stupid jokes and stupid jokes that involve plays-on-words. Sometimes I wonder (or Won-der, if you will) if it's that I'm sensitive to jokes about names, or something. But, really, I just think it's probably more likely that they're just not funny.

All I can say is, thank god we don't have anyone on the van with the names First or Second, because it would be Won (now I'm finding it fun) big Abbot & Costello ride every afternoon to Seattle.
