The Middle S01E04 The Trip.

Socially indifferent Brick didn't bother to protest when classmate Olivia declared him her boyfriend, but soon tires of her 'romantic' demands to the point of despair. Alas, Axl's advise doesn't cut it and Mike is no match for the possessive, selectively girl either but Brick's brain ultimately finds a way out. Eager to see Sue succeed at something, both parents invest ludicrous effort in helping her win a place on a cheap bus trip to nearby Indiana by selling $3,000 food for the school. When her name is absent from the winners list, teacher in charge Perez is not allowed to 'get away with his error', nor with vague promises until it's too late anyhow. Only once Sue is aboard, non-assertive bad example Frankie discovers the real error, with twisted consequences.
