Ouch! Michelle Trachtenberg Rocks a Splint After E.R. Visit—What Happened?

Bandaged actress still manages to make the party rounds after cutting her arm on a broken vase

Just in time for Halloween, Michelle Trachtenberg has that "injured starlet" look down pat.

Unfortunately, that's no costume. The actress has been rocking her one-two punch of bandage and splint all over town this week, and finally took time out to explain her newest unfortunate accessories to fans.

So what happened to her arm?

"1 trip to the ER, 1 splint souvenir, 1 (ish) checked suitcase…still making my flight to NYC, #priceless," she cryptically tweeted on Sunday.

The 26-year-old left her followers in suspense another day—after accepting the well-wishes of concerned pal Kristin Chenoweth—before revealing the cause of her pain.

"Cut my arm open on a glass vase, the word clutz doesn't even begin to cut it. #PunIntended."

Well, you know what they say: laughter is the best medicine. And if you have to crack yourself up to get the effect, so be it.

Feel better, Michelle!
