The 2005 edition of Guinness Book of World Records, includes a category for longest slam-dunk of a basketball from a player bouncing on a trampoline.

Judy Wills Cline became first World Champion on trampoline, in 1964. Cline held a total of ten world titles in trampoline, synchronized trampoline, and tumbling. The first men's World Champion, also crowned in 1964, was Dan Millman, who is a noted personal growth author and speaker.

In 1986, a six-man team from Delta Epsilon fraternity at Cleveland State University, set a Guinness World Book Record for 53 days of continuous bouncing on a trampoline. They received a phone call of congratulations from frater Ronald Reagan.

3. The emotional player versus " classic tennis dinker". Nothing can drive a tennis player more quickly to asylum that having to play a talented retriever who gets everything back with no pace.

4. The obsessive tennis nut -- can't be standing in a line anywhere without starting to practice his or her swing - without a racket of course. Observers often inquire if they're watching some new martial art.

5. The interfering tennis parent -- can't play, never studied game except for having watched an instructional video or two, but feels free to walk on court and correct former Wimbledon champ who is instructing his or her child. Just watching tennis pro try not to explode at this preposterous chutzpah is priceless.

Of course, there are many more of these funny tennis dynamics which I'll address in a later article. So for now, keep your eyes open at club and you may be very entertained by gift of tennis humor happening right in front of your eyes.
