What if US President James A. Garfield and Garfield the Cat switch minds with the help of Alien Space Bats? So, Garfield the Cat's mind goes into President Garfield's body right after his inauguration while President Garfield's mind goes into Garfield the Cat's body whenever you think is the best. So, we now have a US President with the mind of a fat, lazy, and cynical tabby cat who loves lasagna--which I'm presuming you're not going to be able to easily find in the 1881 US--and who also has an aspiring killer waiting for him in a couple of months while you also have a fat orange cat whose IQ massively increased and who could easily become a fine scholar and politician but also whose worldview is stuck more than a century in the past, at least initially.
Anyway, what happens afterwards?
