Mongrelized movie scenes

Take scenes from two or more different movies and put them together for laughs. My example:

In Harry Potter & the Sorcerer’s Stone Wood, captain of the Gryffindor Quidditch team, is showing Harry the balls used in the game. He releases one of the nasty Bludgers. It sails up into the sky, then starts coming back. THEN the bludger sprouts two barbed spikes like the silver sphere in Phantasm, and poor Wood gets spiked in the head.

In Cast Away, Tom Hanks is yelling at Wilson the hapless volleyball. He then whips out his gun from Road to Perdition and blows the little buggar away.
