...Taz, having seen the new (unnamed) cantina is much better than this one is now, completes the movement of all the bar supplies into the new digs.
So GT wants this place destroyed huh?
After giving the situation some thought, Taz decides to really finish the old cantina for good.
Writing a few quick instructions on an Official ACME order form, Taz sends these instructions back 4 years in time.
Taz then places a time lock on the entire star system to prevent interfering time travelers.
Checking his watch impatiently, Taz waits until a mean looking cruiser enters the system. Said cruiser has ACME printed in large letters on its side. It immediately heads for the sun.
Chuckling evilly, Taz then states that the old cantina's bar is now closed and takes off in a whirling motion through the glowing portal.
What was in the ACME cruiser?
Why does even the mighty Taz not dare to stay?
WHY ARE YOU STANDING HERE READING THIS?
RUN!!
