Why do exo-planets always seem to have quick orbits?

Question

This is something that always appears weird to me when reading about exo-planets. They usually have these absurd quick orbits around their star, like a couple of days or two weeks at most. Why is that?

In addition to the other answers here already, consider that most of the exoplanets we’ve found are also huge. Again, it is because it is easier to detect them, rather than because all exoplanets are that big.
