If you've never used an infrared thermometer like the Fluke 561 before, it will seem like magic at first when you do. Just point it at something, pull the trigger, and it'll display the temperature of that object. It's specifically useful in kitchens for measuring the temperatures of cooking surfaces, oven interiors, sauces, etc, or you can use it for HVAC/electrical/mechanical applications.

But let's be honest here: Once this thing's in your hands you're going to use it to scan EVERYTHING AROUND YOU. No matter how bizarre the target, you're going to know the temperature of it: your SO's earlobes; your cat's face; that wall over there; the tree outside; your coffee just after brewing; the same coffee just before you finish it; your keys; the list goes on and on. Don't say I didn't warn you.

The Fluke 561 can measure temperatures from -40°F to 1,022°F (-40°C to 550°C) and has a distance-to-spot ratio of 12:1, meaning it measures a diameter of one inch across at one foot away, 24 inches at two feet away, and so on.
