What is the cutest thing your dog has done?

I have a 5 month old bichon frise puppy who is extremely playful. Last week she went to the groomer for her first “puppy cut.” The groomer said that she did fine with the bath and clipping. However, when it was time to dry her, she proceeded to grab the towel, wrestle with it, and try to “kill” it. It was so cute the groomer took a video of it on her cell phone. What is the cutest thing your dog/puppy has done? Do you think these behaviors have any evolutionary value?
