I've seen 50 seconds on the big-bad-internet with no radio links.  I assume 
it was a link down and some box like my DSL modem didn't flush the queue 
and/or didn't implement the corner of the RFC that says to bump the hop count 
every second..

I routinely see not-quite 4 seconds on the download side of a DSL link.
