Robo was up to something. Something bad.
You see, the other day, he had dug under the floor of a small old room in their house and had set a long underground trail of gunpowder to an out-of-town bank, and today was the day he would light the trail. When Mobo asked just what he was doing, Robo told him with an annoyed tone, "I'm blowin' up a bank! Why tha' 'ell do you think I had all this gunpowder for? 4th of July?"
"Oh. Sorry….." Mobo apologized, his hands behind his back as he kicked the ground lightly. Robo sighed and said, "Sorry 'bout the way I said that. I'm just worried this may not go according to plan." Mobo nodded. He knew his big brother was smarter than him, so he shouldn't bother him with this highly complicated scheme.
Mobo decided to cook some burritos to eat, so Robo could concentrate on his bank bombing. The stout thief grabbed the box of El Monterey beef burritos and popped four in the 'wave. He walked out the kitchen and decided to kill some time by watching The Simpsons . It was pretty funny, as he witnessed Homer strangle Bart per usual. Mobo got a good chuckle out of that.
Robo walked in the living room with several armfuls of moneybags. "I did it! We're rich, as per damn usual!" Robo announced proudly, and Mobo did clapped like a kindergartener. "Yayyyyyy!" Mobo squealed, and Robo kissed him on the head.
"D'awwwwwww…" Mobo cooed.
