And have a sense of humor.
The smart part first.
Some of you may remember I was having problem's with Quincy attacking my son. After trying everything, I still had to keep them separated because Quincy would not get over it. What surprised me was his "lay in wait tactics". My mom would let him out of his cage and take him out every morning, then put him back in the cage while my son got ready for work. If she didn't put him up, he would make a made dash for my son as soon as he opened his bedroom door.

My son started to just crack the door open to see where the dog was, and only come out if it was safe. Then, Quincy figured out that he could run in the house and go straight to the bathroom and wait for my son. Then my son would walk in the bathroom and Quincy would attack!! That amazes me that he could figured out to do that.
As far as that problem goes, my son has moved out!! Problem solved.
Now for the sense of humor part.
Quincy goes nut's with joy when ever someone knock's on the door. He just can't wait to see who it is. So, I alway's knock on the door just to see him get so excited. It's a little game we play. I did it to him three or four time's yesterday. Then last night, I had my arm in the fish tank, and he started going crazy and headed for the door. I asked my mom if someone knocked, and she said no. I opened the door and no one there. Not a soul around. I wondered if he could be messing with me. Then about a hour later, he did the same thing. Again, I got up and looked outside, and no one in sight. Then it occurred to me, Quincy was getting me back. My mom think's I'm nut's, but I swear I think he's playing a joke on me.
Is it possible he's that smart, and has a sense of humor.
