Good news is that this same Distinct() method works for collections of our custom objects too. So if George Clooney accidentally creeps into our collection twice that's derece a sıkıntı:

And yes, after this the output of the program doesn't change at all. So, what the hell is LINQ doing and why doesn't it even try to use the equality comparer that we have provided?
