Sixteen Candles (1984)

Samantha's life is going downhill fast. The 16-year-old has a crush on the most popular boy in school, and the geekiest boy in school has a crush on her. Her sister is getting married, and with all the excitement the rest of her family forgets her birthday. Add to all this two sets of horrendously embarrassing grandparents, a foreign-exchange student named Long Duk Dong, and behold the makings of a hilarious journey into young-womanhood.
