Mt. St. Helens's 1980 eruption was the biggest thing I ever got in trouble for. Really...
Early in the morning, everyone was asleep and the house started shaking, and my father yelled from the other room "quit jumping on the bed!" and I yelled back "I'm not!" and the rumbling didn't stop, the blinds clattering against the windows and he yelled "Dammit! I said quit jumping on the bed right now!" and I yelled, "but I'm not!"...
I was in big trouble... They grounded me practically for life, for not stopping jumping on the bed and lying about that.
Fortunately later that evening we watched the news and I was vindicated... It really wasn't me.
