(Kelly and Tammy both had a crush on kenny and had a rivalry for his affection. But when kenny found out that they both had a crush on him he was beyond happy and he asked them both if they wanted to be in a polyamorous relationship so that both the girls can have him and they were so happy. One day at recess Kelly and Tammy were cuddling kenny under a tree)

Kelly: this is nice

Tammy: agreed, and we both get ken to ourselves~
