my parents live in a really old house, so we used to have a lot of mousetraps... one of my fond childhood memories is of my dad putting dead mice on a shovel and catapulting them across our paddock field yelling "MICCCEEEE IN SPAAAAAAAAAAAAAAACE" and me cracking up...
Lucky. My "fond" childhood memories involve shoveling coal for the downstairs coal furnace (used to heat the house - did a damn fine job, when I didn't forget to stoke the fire and let it go out...) and burying woodchucks in the back yard - I swear, someday the whole region will be flooded, the area will eventually become rock, and millions of years later scientists will wonder at the massive number of woodchuck skeletons in that one little acre of land. ^^;;
My dad didn't want other critters attracted to the region. Besides, can you imagine the puzzled expressions on the faces of the cows in that field to see a big-ass bloodied groundhog flying through the air?
I wouldn't have used a shovel though. No. That would have called for an honest-for-goodness trebuchet. =^-^=
One of my uncles once made a small trebuchet for the purpose of "delivering" a slice of cake to the groom (my cousin) at his wedding. The trajectory was off and the slice ended up plastered to the ceiling.
