Showing off to Jane, Tarzan tied some vines into a Mobius strip but regrettably got caught in an infinite loop. The same question was asked in 2014 on page 34 of this thread, so the length of the loop is about 6 1/2 years. Look forward to seeing this question again on September 10, 2027.
Speaking of 6 1/2, who was Agent X-6 1/2 in "Hide and Shriek"?
