Batman & Superman surprise cancer patients at Texas MD Anderson Center

Pediatric patients at a Texas cancer treatment and research hospital received a surprise visit from some pretty cool guests on Thursday.

In a video posted to Twitter by CBS News, "Batman" and "Superman" can be seen rappelling down The University of Texas MD Anderson Cancer Center in Houston and waving to the children through their windows.

While the pediatric patients were apparently very pleased with the surprise visit, so were the employees.

MD Anderson is ranked the No. 1 hospital for cancer care in the nation by U.S. News & World Report’s 2019–2020 “Best Hospitals” survey.
