How Many Times In A Row Can You Burble?

How many times in a row can you burble?
Can you do it 10 times without a slurble?
100 times with no hint of a gurble?
1,000 times sans a total flurble?!

If you can do something THAT verbal
without a slurble, gurble, or flurble,
I wonder how well I could burble.
