I found this butter in the fridge. Since I didn't do it, and Zac probably didn't do it, I'll blame Izzy. It's not bitten, a butter knife was used to take butter, then it was placed back in the fridge. Izzy is even more of a Julia Child about butter and cream than I am. At least she put it back in the fridge and we didn't find it weeks later in some random place.
