I have to admit, my first thought was "toast". Then I realized that that's what comes <i>out</i> of the toaster, not goes in.
I thought it was a trick question. Now I get it. When you are home all day with three teenagers constantly eating you will "curse" the toaster. You know how many X/per day I wipe up breadcrumbs?...seems they are invisible to kids.
So I asked my kids *the* question. I told them to tell me the first thing that pops into their head. One said toast, one said bread, the other said pop-tarts.
