I need few funny cartoons drawn for a presentation

I am putting together a presenation and the topic is really really dull. However I have come up with a fun story to make it more intresting and want to get some illistrations done to lighten things up a bit and hopefully make people laugh.

These are the image I need to tell the story. The title of the story is "Cart & Yak Problem"

- To guys building a massive cart that can be drawn by a Yak. It's full of bells and whistles (Metaphorically Speaking) (But maybe include a bell or two for a cheap laugh).
- Small Yak looking up terrified at the giant cart. As the cart is clearly to big for the job
- Man standing with a single box at his feet. This is actaully all we needed the cart to carry.
- Stable with three doors behind each is a yak, these yaks get progressively smaller and the doors are labeled, Hulk, Thor and Ant Man.
- Man with lots of boxes at his feet. Can be the same as above just with more boxes
- The cart from above strapped to largest Yak from the stables
- Guy picking a Yak for the job from a catalog
