Rick Sanchez.
He was in his super secret basement lab which collapsed in on him. Thankfully, he had his handy morphine injection to the spine so all those broken bones... he didn't feel it after a while. However, he had to use his portal gun to get out from under the rubble. Once out, seeing what was going on, he would used one of his anti-booby suits to keep himself from getting even more crushed. Then he'd try to figure out how this White Violin person works.
