Timmy tries selling lemonade to see Crash Nebula on Ice, but his lemonade tastes horrible. Timmy discovers that Cosmo's sweat makes the lemonade taste better, and adds it as his secret ingredient. His lemonade is now a success, but with an unfortunate side-effect: it grants the wishes of the people who drink it.

Timmy wishes the great American leaders into his house to finish his report, but because they have vanished from history, the United States reverts to being British colonies. To make things worse, Timmy is unable to wish them back, because Cosmo and Wanda's wands are taken for taxes (Taxation Without Representation). Timmy must now use his Time-Scooter to get them back to their own time period to stop Benedict Arnold from creating the alternate future.
