New Delhi, November 20: Brad Pitt says he may end up in the grave as his kids seem to have resolved to ‘kill’ him and his partner Angelina Jolie by keeping them on their feet at all times.

The ‘Oceans Eleven’ star joked on ‘The Oprah Winfrey Show’ that the kids seemed to have worked out a plan to make sure their parents were not spared even one idle moment.

He said: “They’re trying to kill us! They really are. We’ll get them to bed and one will show up about a half hour later. I know they’ve got shifts, they got it worked out.”

The 44-year-old heartthrob further insists that he’s a strong daddy and a hard one to knock out when it comes to coping up with kids.

Pitt told: “I''m tough as nails. I'm impervious to poo, snot, urine, vomit. You can''t get me. You cannot break me down.”(ANI)
