If you're thinking of using that peanut butter jar, I wouldn't if I were you. Dominic stuck his finger in it to eat the peanut butter. And after he licked all the peanut butter off his finger, he stuck it back in the jar to get more!
So, yeah. Don't use that jar. I think I'm either going to throw it away, or else tell Dominic that it is his jar now and he can't use any of the other jars.
Dominic said that we could just get a spoon and scoop out everywhere his finger touched, but dude, come on. Are you serious?
