Watt is also known for his interactions with children . On July 2 , 2011 , the Berry family was traveling home from a vacation in Colorado Springs . The parents , Joshua and Robin Berry were killed in a head-on collision while also leaving their two sons , Peter and Aaron handicapped . Their daughter , Willa , suffered minor injuries . Watt met the children at a fundraiser and grew close with them . He played wheelchair basketball with them and mimed rolling a wheelchair after sacking a quarterback in a 2012 game . The mime was an agreed upon signal between the Berry children and Watt as a post-sack celebration . In 2012 , following the Sandy Hook Elementary School shooting , Watt found out some of the families that were affected were in the Houston area . He invited them out on the field to hang out and throw the football . He then proceeded to give them signed merchandise that he had worn in previous games . In October 2015 , he dressed up as Batman to surprise kids at the Texas Children 's Hospital for a Halloween party
