Have you ever accidentally done something really embarrassing on Facebook?

Yeah I was joking around with my friend on twitter (which was accidentally still synced with my facebook at the time btw) she knows I'm usually always sarcastic so I don't necessarily need to say it's a joke (we have a really weird sense of humor, which I don't necessarily express with everyone else). To other people it can seem like the things I say are literal if read alone. Long story short twitter ended up posting some reeeally weird stuff on my facebook like I peed in my pants, drive a biscuit, etc. :( I didn't realize until I logged into my facebook the next day and I found my side of the conversation on facebook. I felt really embarrassed..
