there was a spike in dogecoin prices last week, making it the 9th most valuable cryptocurrency: http://www.ibtimes.co.uk/bitcoin-alternative-dogecoin-soars-...
though it's dropped back to 14th since.
with the viral aspect of it, I can see dogecoin actually gaining some traction. It would be funny if it unseats the likes of namecoin, primecoin or other serious cryptocurrencies.
