Group by & Distinct

In a query that has a 'group by' , will a 'distinct' give any different result?

As a group by will group all same values into one row, I think the distinct will not change the result set.

Is this correct? If not correct would appreciate a sample query and data sample where the above is not true.

Thanks,
