Sure we can, but if we let jQuery create a callback function, it will always be different. This is to let Yahoo cache the results better, as per this [YQL Blog post](http://www.yqlblog.net/blog/2010/03/12/avoiding-rate-limits-and-getting-banned-in-yql-and-pipes-caching-is-your-friend/). I am a bit skeptical though, since that article is 3 years old and I haven't seen a discernable difference.

If you like, I will remove it.
