returning and using multiple models in MVC

I've been able to successfully return a model to a view and display the results in a strongly-typed fashion.

I have never seen an example where multiple models get returned. How do I go about that?

I suppose the controller would have something like this:

return View(lemondb.Messages.Where(p => p.user == tmp_username).ToList(), lemondb.Lemons.Where(p => p.acidity >= 2).ToList());

Does MVC let you return multiple models like that?

And then in the view I have this line at the top of the file:

@model IEnumerable<ElkDogTrader.Models.Message>

And I frequently make calls to "model" in the view.

@foreach (var item in Model)

If there were 2 models, how would I refer to them separately?

Is this possible with multiple models, or is this why people use ViewBag and ViewData?
