I’ve been known to eat Easy Cheese right out of the aerosol can and into my mouth. No, I’m not proud of it. (To those of you who don’t know, Cheez Whiz comes in a jar, not a can)
I like to eat pickles out of the jar sometimes, but I think that’s pretty common. Olives too, but also fairly common.
If I’m hard up for some protein I will eat tuna right out of the can too. Also not too bizarre I guess.
