Saving your wood glue

I just went out into the garage to do some work and found my wood glue pretty messy ... thick ... clumpy ... just a mess.  Well, I didn't want to buy new glue (hey ... I'm cheap) so I added about an ounce of water, opened the top, put it in the microwave, put it on "soften chocolate" mode for about 20 seconds, and it came out toasty warm.  They I stirred and shook it for about 10 minutes and it seems as good as new.
