You can put something on the left,  
like a list of wheat beers.

**Wheat Beers**

* American Dark Wheat Ale
* American Pale Wheat Ale
* Belgian Witbier
* Berliner Weisse *
* German Dunkelweizen
* German Hefeweizen
* German Kristalweizen

And hey, there's a &#x1F37A; over &#x1F449;

.pull-right[

Think of something _extra_ **witty** to say about beers.

Either `4:3` or `16:9`
