You can use an egg timer to tell you when your egg is cooked perfectly. For brown rice you can use a calendar.

Commentary:
"Who knew cooking brown rice required a schedule 📆 while eggs just need a quick timer ⏲️? Brown rice be like 'Hold on, let me check my calendar before I get all chewy and clumpy!' 🍚🤣 #KitchenConundrums"
