Transform collection of objects to a collection of tuples

I have a collection of objects. I've made sure it has an even amount of objects.

Object1
Object2
Object3
Object4
Object5
Object6

I need to transform the collection to tuples, like this

Tuple(Object1, Object2),
Tuple(Object3, Object4),
Tuple(Object5, Object6)

I've been trying to come up with an extension method for it, but I haven't figured out anything.

public static IEnumerable<Tuple<T, T>> ToTuples(this IEnumerable<T> objects)
{
    // what do I do here?
}

Something like this maybe?

  public static IEnumerable<Tuple<T, T>> ToTuples<T>(this IEnumerable<T> objects)
  {
     IEnumerator<T> enumerator = objects.GetEnumerator();
     while (enumerator.MoveNext())
     {
        T object1 = enumerator.Current;
        if (enumerator.MoveNext())
        {
           yield return Tuple.Create(object1, enumerator.Current);
        }
     }
  }
