how do I infinite loop (reconnect) to auto disconnect telnet server

I want the text based Star Wars movie at towel.blinkenlights.nl to loop infinitely.
It plays the movie and then disconnects my session? Can anyone think of a way to make my unix machine automatically reconnect over and over?

EDIT

no commands are required are the connection its just in and wait and then it auto disconnects.

Nevermind, I did it like this:

Code:
#!/bin/sh
# Loop Star Wars forever
while :
do
#Do whatever you have to do
  telnet towel.blinkenlights.nl
# Sleep one hour
  sleep 3600
done # Start over

Also you can check when telnet session disconnect which is the $?(exit code) of it.
Then you can test that output, instead of counting the seconds.

That way if they make a sequel which last 3700 seconds, you won't have to modify your script Smilie

Worth building in a way of stopping the process.
To stop the process, delete /var/tmp/stopme

Code:
touch /var/tmp/stopme
while [ -f /var/tmp/stopme ]
do
        telnet towel.blinkenlights.nl
done
