Tank Girl (1995)

Continuity mistake: When Rebecca makes her boyfriend strip, you can see the gun's laser on his hand before she comes around a corner and points the gun at him.

[Tank Girl is holding the madam of Liquid Silver hostage and is being threatened by the guards.]
Tank Girl: Everybody drop your guns, or I scrape off all her make up!
[Considers the madam's face.] This might take me a really long time.
