Movie People escaping through toilet stall

[Lepus]

I remember this scene from some movie, where some people are being chased and they escape
into the bathroom and in one of the stalls theres a dummy old lady sitting at the toilet and it flips over and they escape through a trap door. Can someone remember the name of the movie.

I too remember this scene but can't recall the movie. At first I thought it was Ice Pirates but I was wrong. Can you remember anything else about the movie.

It took me a few min to think about it but the movie your looking for is Space Truckers from 1996 watch around the 22 min mark you will see the part you were talking about.
