I found out last night that no one around me has been understanding my great joke. I have been using "a metric butt-ton" as an exaggerated unit of measurement. Ie: I drank a metric butt-ton of water. Turns out that no one around me knew that butt is an actual unit of measurement, but an English one for half a ton of wine, and so calling it a metric butt ton seemed really funny to me. Turns out ONLY funny to me for that reason. Other people just thought it sounded funny.
