Solution 1:

To remove a cookie, do the same thing but set an expire date in the past:

In this case:

document.cookie=”PREF=ID=20b6e4c2f44943bb:U=4bf292d46faad806:TM=1249677602:LM=1257919388:S=odm0Ys-53ZueXfZG; expires=Thu, 01 Jan 1970 00:00:01 GMT; path=/; domain=.google.com”

The key is the addition of expires=Thu, 01 Jan 1970 00:00:01 GMT;
