The rich guy was eating a delicious fancy meal while the poor guy only had slop.
**Poor guy**: “Hey, wanna swap ?”
**Rich guy**: “Why would I trade my delicacy for your slop ?”
**Poor guy**: “This isn’t ordinary slop, it’s a secret family recipe. Whoever eats it becomes smarter.”
**Rich guy**: “Really ?”
**Poor guy**: “Yeah! Try it for yourself!”
The rich guy gives his food to the poor guy and takes the slop. After eating a spoonfull he turns to the poor guy.
**Rich guy**: “Wait a minute! You tricked me so you can take my lunch!”
**Poor guy**: “Well the slop worked! You did become smarter!”
