Mrs. Swanson (AKA "Joe's Mom") is the biological mother of Joe Swanson, the adoptive mother of Janine Bananas, and the wife of Bud Swanson. Furthermore, she is also the grandmother of Kevin and Susie Swanson and the mother-in-law of Bonnie Swanson. She bears striking resemblance to her son. During her lifetime, she was a retired old woman in a wheelchair, either due to senility or paraplegia. She first appeared in "Boopa-Dee Bappa-Dee".
In "Brokeback Swanson", a crazed mental patient screams at Joe, telling him his mother's a whore. Joe replies, saying "I told you that in confidence, Gary."
- In "Papa Has a Rollin' Son", it's learned that Joe's father Bud Swanson has no respect for cripples and would resent one being in his family. However, Joe's mom was shown to be in a wheelchair in "Boopa-Dee Bappa-Dee". It would seem unlikely for Bud to marry a cripple if he was so against them. However, it can be implied that Joe's mom is not "crippled" per se. She's just in a wheelchair cuz she's old.
