Yanking multiple times

[Balaji Venkataraman <bvenkata+nospam@sm.intel.com>]

How does one yank the same line multiple times?  e.g. - do a C-a, C-k and
then paste the same line 20 times (of course I don't want to hit C-y 20
times). I understand that a numeric argument to C-y, goes back into the 
kill-ring by that much, rather than repeat the command.

I tried info and google, but found nothing.
