Bowser is in the dining room for breakfast.

Bowser: Hey chef. What's the lunch today?

The chef hands him the breakfast menu.

Bowser: Chicken, chicken, chicken, is this all you can cook?

Chef: Yes.

Bowser kicks him out a window.

Bowser: I guess I'll go cook something.

Goomba: But sir, you don't know how to cook.

Bowser: Fine. I guess I'll make a sandwich.

A few seconds later...

Bowser: This is too hard!

Goomba: But you're not even in the kitchen yet.

Bowser: Oh. I knew that.

In the kitchen...

Bowser: Okay, let's see... Bread...

Bowser grabs two planks of wood.

Bowser: Meat...

Bowser puts on spoiled meat.

Bowser: Sliced up tomato...

Bowser slices up a rotton tomato with his claw. He puts the sliced up pieces on the "sandwich".

Bowser: And ketchup.

Bowser pours on red-colored rocket fuel.

Bowser: Now to heat this up.

Bowser breathes fire all over the sandwich, causing an explosive reaction. The explosion sends the sandwich's horrible stench all over the castle. Bowser Jr. stumbles in.

Jr: Erg... What's that stench?

Bowser: My sandwich.

Jr: Well it stinks!

Jr. faints.

Bowser: ... I knew I should have put more ketchup.
