Rick Rolling (слэш)

During a boring thoery lesson, Harry starts humming a song that he heard on the radio over the summer, one that he found particularly catchy and can't seem to get out of his head. He didn't mean to cause a distraction and he certainly didn't expect anyone to hum the next line back.
Can Harry accidentally Rick Rolling Snape be the catalyst for a much needed reconciliation between the two? Of course it can, this is me we're talking about.
