Weak Analogy

Is committed when the arguer uses an analogy to support the conclusion, but the analogy is inappropriate.

My old car was blue, and had cloth seats. It also got great gas mileage. I want to get a car with good gas mileage again, so I'm buying Mike's old Dodge Quad-Cab pickup. It's blue and has cloth seats.

This fossilized skeleton has a jaw bone similar to that of a horse. It's teeth are also quite similar, as is the abdominal cavity and feet. So it was probably a herbivore, like horses are.

Giraffes and gorillas have fur, eat plants, and have names that start with Gs. They are also very large. Guinea pigs also have a name that starts with a G, have fur, and eat plants, so they are also probably very large.
