In this episode, Dexter tries to make himself older so he can stay up late to watch a film with his family. However, Dee Dee's meddling with the Acceler-Ager turns him into a 95-year-old man.
Dexter wanted to using his Hydro-Cosmetic Accelerator to age himself enough so he could watch late night television without his parents objecting and he keeps getting rejected because he was too young. Dexter tries to make himself 21 years old, However, due to Dee Dee's involvement, the device aged him way too much, turning him into a 95 year Old Man Dexter, who complained constantly, had numerous health problems and suffered from forgetful senility, often calling Dee Dee by different names. Lucky for him, his parents and Dee Dee were oblivious to his true identity, instead believing him to be Grandpa. Dexter, however had no objections when it was finally time to watch late night television, but much to his misfortune, he ended up falling asleep due to his advanced age making him unable to stay up all night. Eventually Dexter was able to undo his aged transformation.
