Wonder no more. Enter three or four words and Google will finish your thoughts by searching for what comes next after these words.
Use Google talk by entering three or four words below. The system will search for this sentence at Google, find the next word and print that. Then it will remove the first word of the search string, add the found word and repeat. The result seems to be meaningfull sometimes. Other times it is giblish. But always fun.
If you use it, and you get something good|funny|weird, leave a comment!
