When dealing with time-traveling toasters, it's easy to get carried away. Don't. You'll only end up causing paradoxes and attracting unwanted attention from the Temporal Integrity Commission.
Stick to your mission parameters, no matter how dull they may be. Your toaster has a purpose, and that's to toast bread. Not to prevent the rise of the Roman Empire or stop the invention of the printing press.
Remember: time travel is not a game. Unless you're playing "Time Traveler's Quest for More Toast," then it totally is.
