Spazz the visual cracks me up - scrawny spazzdog - in a former life I was VERY skiiny - scrawny even - and sort of hyper (maybe I was a little hyperthyrod? wish I still was!) - my co-workers teased me that when I was drinking coffee (and BOY did I drink coffee!) I was "Achieving Chihuahua-ness".

Your "spazzdog' moniker just reminds me of that....
