OK, one last try on the horse...

I'll say Gigolo. According to this link [http://equestrian.medianotes.com/reports/2000/stuttgart.htm] he won 5 medals (2 individual silver, 1 individual gold, 3 team golds). But the wording is hard for me to understand...appears to be a translation from the German ;-) Also to add to the confusion, I found another link on the net that said Gigolo only won 5 medals.

I've really learned a lot about equestrian events, so I'll watch on Sunday, I think. (I've also learned to READ THE QUESTION and check the dates on the webpages.)
