I think this is great, but is my surprise at this only because I haven't been listening to ESPN Radio? Does this happen all the time, an advertisement in a different language from the program it's placed in, and I just haven't been paying attention? I haven't heard this kind of multi-lingual imbedding since Singapore, where Mandarin ads sometimes appear in the middle of English-language programming.
(The other odd thing about it is that the Spanish-language ad gave baseballtomorrowfund.com as a URL, and the whole page is in English. I can't find a Spanish-language link, except one buried in a pulldown to MLB Español. This seems like a bad plan.)
