The Simpsons
Marge is cast in a version of "A Streetcar Named Desire," playing Blanche to Ned Flanders' Stanley.

Used to express surprise, admiration, or ironic disbelief. Tone is determined entirely by context and intonation: it can be genuinely impressed or sarcastically dismissive.
When used as an outburst (not literally asking someone to forget information), it signals the speaker is giving up, dismissing a situation, or storming off. The literal meaning of 'forget it' does not capture this emotional force.
Non-compositional because 'contar' alone means 'to count' or 'to tell a story', but 'contar con' shifts entirely to mean 'to depend on' or 'to have available'. The preposition changes the meaning completely.
Fixed phrase used to assert that evidence or results are so clear they need no further comment. Sounds more self-satisfied in Spanish when used in first-person defense of one's own work.
Used ironically or as bravado to mean the speaker is so committed they disregard the risk, or simply that they don't care at all. The direction of irony depends on context: here it signals reckless passion rather than indifference.
'Meterse' literally means 'to insert oneself' or 'to get into', so 'meterse en la cama' is idiomatically used for going to bed in a resigned or deliberate way, often implying retreat or escape.
