The fan who did this one was a genius! Even though the alien was only shown once and on a rather lame and early episode…”The Corbomite Maneuver,” (sad I know it), which also had Cliff Howard as the guest star…its picture was often shown in the closing credits. When I was a smaller kid, it scared the crap out of me because Star Trek was also shown late at night on Channel 3 (WCIA, Champaign, IL). Today, it’s funny and Futurama did a similar joke with poor Kif when the primary cast of Star Trek were the guests.
