I finally got her laughing at me... and pretty hardy, too! She likes my doggie impressions. She does a pretty good doggie impression herself, too, as you can see in the second video of her.
I even got her laughing like this (well... she was laughing at the water bottle, really) in the waiting room yesterday at my doctor's office. All the people in the waiting room and the receptionists got a big kick out of her hardy laughs.
