Ask HN: Funny Startup Anecdotes?

One time I accidentally charged a customer $5,000 instead of $50 because the Stripe API takes cents (which would be 5000), and the UI takes $. I entered 5000 into the UI because I was so used to using the API. Still scrapping around manually charging customers because we weren't all the way automated yet.

Called up the person and told them what happened and refund was on the way...they didn't seem too worried. haha...

Was exchanging stories with someone today and wondering if anyone else had some funny stories to share?
