 CONT: When the pipe rolls toward Mr. Potato Head while crossing the  road, there is one shot from behind the pipe. At the rate it was  rolling, it would have smashed him right away. However, we see  Potato Head freeing himself from the gum, which took a few seconds.  Moreover, when Potato Head walks from the gum, he has a fair amount  of time, and the pipe is further away than it originally appeared.
