As the image shows, one of Hill's hands is occupied holding a Bud Light bottle, indicating he had some idea of what to do with one hand at least. However, the primary remark seemed to be a nod towards a character portrayed by Ferrell - Ricky Bobby from Talladega Nights: The Ballad of Ricky Bobby.
In Talladega Nights, Ricky Bobby admits, «I felt like I was on a spaceship. I'm not sure what to do with my hands.» The following clip humorously continues with Bobby's indecisiveness about what to do with his hands.
This quote from Hill might initially come across as strange. Yet, considering the fact that he had just clinched a Stanley Cup, it is quite fitting - more so when you take into account the apparent homage to a beloved comedy film.
