One time my dog was in the back yard playing with a chew toy (he always leaps around and tries to pounce on them until he realises what they are) when he jumped and smacked his head right into the table

He then swung round and started attacking the table leg for a bit...
One other thing which I didn't actually witness but I've heard the tale many a time. My oldest brother was round his mate's house with some friends,
recreating and one of them dropped some speed on the floor. The guy's cat (lovingly named "Pussy") walked past, gave it a sniff and proceeded to lick it up off the floor. Needless to say the poor thing went mental for a couple of hours, racing round the flat, actually scaling the curtains, running along the curtain rail and back down only to start the whole thing again. They've been much more careful these days I hear.
Jam it back in, in the dark.
