Roy Horn grew up in Nordenham, Germany where he developed his love for animals.After being rescued from quicksand by his half-dog, half-wolf pet named Hexe, Roy joined the team of pet trainers at Bremen Zoo.He’s wearing crisp white pants and a dress shirt – the collar turned up rakishly – and a black and white blazer. Two fans, looking hot and sweaty despite their sleeveless shirts, flank the entertainer and ask him to pose for a photo.

Instead, they strive to remain relevant, in the here and now.

Like Little Bavaria itself, they are still growing, in their personal and professional relationship.

Roy -- who was mauled by a tiger in 2003 -- has been going through rehab to strengthen his left side.

But the physical therapists tell us, Roy's right side is "extremely strong," and the video clearly shows Roy sexually assaulting the male therapists.

The video -- shot in 2010 -- shows the following:-- As a caretaker helps Roy to the bathroom, Horn shoves his hand into the man's butt crack in an aggressive manner-- On another trip to the bathroom, Roy thrusts his rear end into the male caretaker's crotch-- In two clips, Roy grabs the genitals of two male caretakers-- Roy goes under the shirt of one caretaker and appears to tweak his nipples.

The caretaker appears to writhe in pain-- It appears Roy gets frustrated with one of the caretakers and violently whips him with an oxygen tube -- Roy manhandles one of the caretakers and forcibly kisses him on the mouth The 3 male caretakers in the video tell TMZ they are all straight and have families.

Siegfried also enforced the construction of a new house outfitted to offset Roy’s physical limitations, suffered a decade ago when he was dragged offstage by a white tiger named Montecore during a performance at the Mirage.

October 3 marked the 10-year anniversary of that incident, which Siegfried and Roy alternately refer to as “the accident” or “the thing,” as in, “When the thing happened ...” But they hardly speak of it, and only when asked.

It’s as if he has a trick air conditioning unit up his sleeve.
