RKO's "Secrets"

Before becoming a wrestler, Orton enlisted with the United States Marine Corps. Orton was dishonorably discharged about a year later after going AWOL on two separate occasions, and disobeying an order from a commanding officer. Under the Uniform Code of Military Justice, Private First Class Orton was tried and convicted under a special court-martial, and was put into a military prison for thirty eight days.

While on RAW, Orton was accused of harassing fellow WWE employees Amy Weber and Rochelle Loewen, leading to the departure of Weber from the company, while Loewen was transferred to SmackDown! (she was later released). Loewen (who has called Orton "an animal") claimed that he vandalized her possessions and subjected her to harrassment. However, it should be noted that Orton's friend Mark Jindrak refuted several of Loewen's accusations in an interview with Voice of Wrestling, and claimed that Orton had apologized to Loewen at the time of the 2005 Royal Rumble, and that fellow Diva Search contestant (and eventual winner) Christy Hemme denied what she knew of the allegations in an interview with The Sun.

Orton suffers from hypermobile shoulders.

In November 2005, Orton announced his engagement to his girlfriend Samantha Speno. They will be married in the fall of 2007.
Orton has got a tattoo of his fiancée's name on his right arm. He also has designed signature tattoos on his wrists, upper biceps and on his upper back finishing his shoulders.

His mother is Elaine Orton.

Orton's three favorite matches are: Shawn Michaels vs Bret Hart - WrestleMania XII - Iron Man Match, Shawn Michaels vs Razor Ramon - WrestleMania X - Ladder Match and Randy Orton vs Mick Foley - Backlash - Hardcore Rules Match.

On March 19, 2007, Sports Illustrated posted on its website an article in its continuing series investigating a steroid and HGH ring used by a number of professional athletes in several sports. That article mentioned several current and former WWE wrestlers, including Orton who was alleged to have obtained clomiphene citrate and the steroids stanozolol, nandrolone, anastrozole, oxandrolone, and testosterone. WWE has since made a statement on this situation, mentioning that the allegations preceded the Talent Wellness program WWE launched in February 2006.
