Thonk & Whack
Professor Quanticus’ time travel helmet was proven a success when his last communication with family was a final photo sent from the past. While traveling back in time he discovered the first ancestors of his diabolical family, Thonk and Whack. With what can only be assumed was his final act, he took a photo of the perturbed couple, stuffed it into his helmet, pressed the “on” button, and then promptly met his doom at the end of a large blunt object wielded by a raging slack-jawed cave dweller and his grumpy wife. RIP Professor Q.
