The context of the following conversation is Robin was making breakfast before work and felt his oats to ensure they were the right temperature.:
Robin says And this is how I can tell that the oats are the right temperature..
The friend responds Gross. You put your finger in them?.
Robin responds Well, yes. I am going to be the one eating them after all. What, do you think I would use a thermometer?.
The friend responds Hm, I don't know, but putting your finger in wet food is definitely gross..
