In a Wendy's training video from the 80s, a rapper shows a new employee the ins and outs of cooking burgers.
The employee activates what looks like a microwave, causing it to rumble and emit the morphing head of a singer. The employee is sucked inside and reappears in a club-like version of a Wendy's kitchen.
The rapper then takes the worker through each step of preparing a Wendy's burger. At one point the burger patties themselves sing encouraging words.
No, really. Don't just take our word for it.
