Bill & Ted's Excellent Adventures (1990) - 1x07 - A Black Knight in San Dimas- Followmy.tv

Bill & Ted are rehearsing for Wyld Stallyns to play at the school dance (no one else tried out). They arrive late at school and accidentally slip into the girls' health class during a movie and are caught by Miss Spleen, who reprimands them for being late for her math class and forgetting homework and threatens to have them expelled and kept from playing at the school dance. Later at the Kozy Korner, Ted purchases a blue Frosty Slush in a silver collector's cup before the dudes head back in time to pick up the Princess Babes to sing with the band at the dance. They accidentally end up in the middle of the Crusades where they run afoul of Saladin. He is ready to arrest them until he spots Ted's silver collector's cup and believes it to be the Silver Chalice. Just then the Black Knight bursts in and steals the Silver Chalice for himself. Believing Bill & Ted crossed them, Saladin's men start after them but they are able to escape in the booth. They arrive in England just as the Black Knight returns from the Crusades with the Silver Chalice as a gift for the king, who offers the Knight one of his daughters in marriage as a reward. Determined to save the babes, Bill & Ted infiltrate the castle and dress as jesters to entertain at a banquet. Their feeble attempts at juggling and magic acts tips off the Black Knight, who announces they are there to steal the Silver Chalice. The dudes manage to get away and sneak into the rooms of the Princess babes, where the Black Knight shows up and demands Joanna's hand in marriage. At the wedding, the princesses are saved when Rufus disguises himself as Joanna long enough to allow the dudes and babes to escape. Chasing after them, the Black Knight is sucked into the time circuit and swept along to San Dimas with them. At Ted's house the Black Knight lands on the roof and crashes down through the chimney. They keep him in a state of unconsciousness by playing Lawrence Welk polka classics for him. Bill & Ted leave Deacon
