A presumably lubricated Robert Pattinson stumbled his way through a tribute to his 'Water for Elephants' co-star Reese Witherspoon at the MTV Movie Awards on Sunday, flubbing teed-up punchlines and dropping an epic f**k-bomb that proved too nimble for censors.

Following a short speech by Patrick Dempsey, R.Patz appeared confused when it came time for him to speak about Witherspoon, who was receiving the Generation Award. After some inaudible giggling and a "This is the worst" observation by co-presenter Chelsea Handler, Pattinson began telling about the first time he worked with Witherspoon.
