<Li> Nick Katsopolis ( played by John Aprea ) is Jesse and Pam 's father and maternal grandfather to D.J. , Stephanie , and Michelle . He is an avid fan of Elvis Presley , just like Jesse . Also , like his son , he is very much interested in his hair and women ( as he states in the season two episode `` Our Very First Christmas Show '' , `` there are two things Katsopolis men are known for : kissing and great hair '' ) . Nick is the owner of an insect extermination business . He met his wife , Irene , the day that Elvis was drafted into the United States Army . Nick was a firm but caring parent . In the episode , `` D.J. 's Day Off '' it is mentioned that he would punish Jesse severely . This combination is also seen in the episode `` It Is Not My Job '' , when Jesse quits the extermination business Nick responds with : `` If you 're out of the business , you 're out of the family . '' Later on , he explains this by saying that he did not build up the business to sell it to a stranger . His love for his family is also shown by the fact that Irene bringing in Michelle curbed his anger . When Michelle was getting ready to do a television commercial for marshmallows in the season two episode `` El Problema Grande de D.J. '' , he remarked that Michelle looked like a little blonde version of the redhead he likes on Gilligan 's Island , which was revealed to be Tina Louise by Irene . In honor of inheriting Nick 's hair , Jesse names one of his twin sons after him . Nicky and Alex never interact with their grandparents on - screen like the girls have , as Nick and Irene are last seen in season four . Nick re-appears in season three of Fuller House when he comes to take care of Tommy while everyone else goes to Japan for Steve 's wedding . Nick mentions to Tommy about going out to find women , so it is assumed that him and Irene are no longer together or she is no longer living . </Li>
