Apparently in Transformers, the cast used silver rods with tennis balls attached at the ends to fill in for the robots, which would be CGI’ed into the scene in post-production. MTV VJ Damien Fahey handed Shia a tennis ball and they had a love scene together!
Damien voiced the character of the blonde-wigged tennis ball while Shia played his handsome himself. Shia gave it all he got — he grabbed his rod tightly, used his tongue to start licking the tennis ball, started rolling all over the floor with the rod and kissed the tennis ball to death. (It’s even funnier if you just watch it.)
Watch the video below of Shia getting his lickin’ on…
