Jeremy Johnson is a teenaged boy from the Disney Channel animated series Phineas and Ferb. A semi-frequent participant in Phineas and Ferb's big ideas, he is Candace Flynn's love interest, and it is pretty obvious that he feels the same way about her as well.
In the series' first Christmas special, Phineas and Ferb Christmas Vacation!, Jeremy is urged by Candace to write a letter to Santa Claus, completely unaware that she's desperate to find out what he wants for Christmas. When Candace is unable to read Jeremy's letter, though, she tries to convince him to do some window shopping with her, but it only confuses him. In the end, Jeremy later comes to Candace's house to give her his present for her - a pair of earrings that she wanted, which he had to sell his old guitar for in order to buy. In return, Candace, who found out Jeremy's Christmas wish while helping her brothers save Christmas, presents him with a new silver guitar.
