Funny story here on wbez.org, about Chicago swimming legend Johnny Weissmuller famous for being first man under the minute in 100 meter freestyle, and for his role as Tarzan in the 1930-ies and 1940-ies.
In 1958, years after his last movie, Weissmuller was at a golf outing in Cuba when his party was suddenly captured by rifle-toting rebels. Johnny smiled at them, then let loose his famous movie jungle-yell. The rebels stopped, smiled back, and began calling out “Tarzan! Tarzan!” Then they gave Johnny an armed escort back to his hotel.
