How to detect two overlapping date ranges with the same primary key?

I have a table that looks kind of like this:

PKey StartDate EndDate
0 2016-01-01 2016-02-01
0 2016-01-31 2016-03-05
1 2016-01-21 2016-01-18
1 2016-01-19 2016-02-01

As you can see, there are two overlapping date ranges for PKey 0. I want to return the second one.

This query just returns rows that have two StartDates and EndDates that are exactly the same:

SELECT * FROM
productcosthistory t1
JOIN productcosthistory t2
ON t1.productId = t2.productID;
