When I was younger I had a hamster named Loki, and he was the craziest little bugger!
He got loose twice (well, two memorable times at least).
The first time he was gone for about three days, where did we find him? In the basement (mind you, this was an old house, you had to go outside to get into the basement), in a five gallon bucket. There was nothing on either side of the bucket, it was in the middle of the floor, and there was Loki, staring up at me from the bucket chasm like it was any other day.
The second time he was gone for about a week. I kept putting food out, and it kept disappearing. Well, finally, my step mom was making dinner one night. I heard her screech about a sound coming from the oven. My dad opened that drawer thingie under the oven, and there again was Loki, acting as if it was the most natural thing ever to be sitting in an oven drawer.
*Sigh* I really do miss that hamster, he had some serious personality, but I agree, mischievious acts must be linked by the name!
