He also lied to her about not being the father of Amy's baby when she asked for his help at the abortion clinic.
- He would have sex with girls and then try to completely avoid them afterward. The only girls he was shown to try and hook up with again having sex were Amy and Adrian. Shawn is also implied to have had sex with him and he did try to hook up with her again, but it was never explicitly confirmed that they had sex.
- It is shown in the first episode Ricky pays Joe Hampton to do some of his assignments for him. With this information, it can be determined that Ricky did not deserve the "Governor's Award" or to be "Valedictorian".
- He tells every girl that he sleeps with that "He loves them".
- He lives with his fiance and his son in his apartment above the butcher shop.
- His father abused him when he was young, and uses that incident to explain why he has indiscriminate sex with several women.
- He works with Ben in the butcher shop.
- Ricky seems to be one of the weaker emotionally based male characters on the show despite the hardcore exterior he tries to project to others. This makes him be more sensitive because he cries a lot during the series.
- In Season 2 of the show, he began to flirt with Ashley Juergens, Amy's younger sister. Although she is John's aunt he claims that they were only friends, and stops returning her advances in the beginning of Season 3. He claims that he wants to start a relationship with Amy so she can love him, and later avoids Ashley completely.
- He has never really been able to support anyone emotionally save for Amy, and Grace. Totally abandons both Adrian and Ben after the death of their child.
- He claims that he is friends with Ben Boykewich, but it is shown that their friendship is really a rivalry in which Ricky continues to show Ben he is better than him at everything. He makes a statement to Ben in Season 1 claiming that "He would have his father, Amy, and the baby on his side before he could say pork chop".
- This rivalry has gone on from not only Amy and Adrian, but also so he could have the better relationship, and the better kid. It also extended to Ben's father and Boykewich company in General. However Ben has made it clear he does not want to run his father's company. Ricky wants to run the company, but will most likely drive it into the ground.
- In the Season 4 episode "And Circumstance", it is revealed that Ricky had a GPA average
- In the Season 5 mid season finale "Half Over", Ricky tries to intimidate Ben in the hospital about not revealing the secret about him and Amy. He tells Ben that Amy has John, Ben does not have a chance. This statement presumably has a strange effect on Ben who admits he is right.

- Ricky is working with Leo to create a high-end fast food chain.
