Okay, I guess Ripley is just being dominant. I just wondered since he is really into sniffing her or where she's been sitting. I think the stress of Scout - who is female - coming in and being dominant over him has just made him feel he has to exert his dominance over someone, poor Jazz.

As for Ripley and the Oscar the Grouch hand puppet - I'm certain he really used to hump it. He'd bite Oscar right behind the eyes and drag him around howling and then go to it with the hip action and his "lipstick" out - if you know what I mean.
