On 'Making History' Dan had gone back in time and met the lovely Deborah Revere. Having successfully wooed her with tales of all his great inventions, like the television and the skateboard his lies were finally catching up with him when, in the present, Deborah realized that Dan was not the original singer of Cher's "Turn Back Time."
With a now angry Deborah going off into "yon woods," Dan decided he needed to turn back time to ask Sam Adams and John Hancock how to win Deborah back.
After regaling Dan with stories of killing off competitive suitors, they suggested that Dan give Deborah the performance of a lifetime.
Donning all the gorgeousness of Cher, Dan went off to the woods to find his love and sing her back but the performance got put on hold when Cher Dan fell into one of Deborah's traps -- like a literal trap. For bears and stuff.
Though the Cher plan failed, the gesture was enough to win back Deborah and he managed to give her the original song she deserved with all original "smoking hot in that corset" lyrics.
