user7171: I'm making like nothing off these guys and am looking to use them for something else.  I guess these ASICs are designed for SHA-256 hash function based cryptocurrencies.
Try to mine Terracoin?

user7397: There's piles of different coins to mine.  Figure out which one is most profitable to mine: http://www.coinwarz.com

user16: Unfortunately these small asics will eventually be useless unless you want to keep one or two around on the off-chance that you will want to start your own crypto-currency.
However, if you have a pile of 10-20 of them setting around, you could use them as an opportunity to teach people about Bitcoins and how the system operates.  
Handing out erupters that you no longer need could be a good way to pique the interest of people who have heard of bitcoin, but have never taken a good look at it.
Other than educational purposes, or seeding new cryptos, I see no long-term use for these low hash power ASICs.

user1307: I use mine in "lottery mode" as I call it. 
They don't really consume too much energy, so I just let them solo mine. Big chance will turn out to be nothing, but with some luck they will ever find a block and cash in 25 BTC.
How low the chance may be, it's still a lot higher than winning the ordinary lottery and way cooler :)
EDIT: A quick calculation of your odds.
The current (2014/01/24 23:07) chance of a hash to be a winning hash is 0.0000000000000000001061272725905534506860017351925762341. Then the odds of winning each day are for one block erupter USB of 330MH/s
0.0000000000000000001061272725905534506860017351925762341 * 330*10^6 * 60*60*24 = 1 / 330480.1
So one chance in 330,480 each day or one chance in 905 a year (of course, changing difficulty has to be taken into account).
Let's take the Powerball lottery as a reference as Earlz mentions, it has odds of one in 648,975.96 to win $10,000 one in 5,153,632.65 to win $1,000,000.
So, every day you have double the chance to win 25 BTC than you have to win $10k, which is less and costs you probably a dollar or two to enter.
