So many adorable stories!!
I once had a Bichon who loved 2-liter soda bottles. Once the soda was gone, we'd take the label off and screw the cap on really tight. By this time Penny would be going out of her mind with anticipation. Then we'd throw it down and she was off - chasing this huge, bottle around trying to get her mouth around it.

She'd eventually get it into a corner where she'd just keep pouncing on it trying to bite it. When she got tired (exhausted), she'd grab the bottle by the cap and take it somewhere "safe" to snuggle with it.
My first cat, Stanley, loved my DS so much. He'd sit outside the bathroom door just staring at it until DS would come out. DS had to push his pillow to one side of his bed so that Stan could lay right next to DS's head - every night.
My cat now, Bear, loves to play in his water bowl and get the kitchen floor soaked. He figured out how to drink from the bathroom spigot and, for a while, that was the only way he'd drink. I'd have to turn it on just so that it trickles out. He'd turn his head and drink til you'd think he would puke.
Bear's latest obsession is the humidifier. He'll sit there and sit there (I really do believe that he was up all night the first night I had it on - he looked pretty darned tired the next morning) and wait for the bubbles in the resevoir. Then he jumps up and tries to "catch" them.
