The Quick Stash Moustache was seen in "Evil Airlines Much?". It is used to hide objects, but can easily grow too large to be useful.
- When trying on the gadget, Alexandra and Samantha quickly toppled over due to the weight of the objects they tried hiding under it. Annoyed, Sam sarcastically said quote that the mustache sure was "foolproof" and that "no one would ever suspect anything being hidden under it."
- Alexandra asked Jerry why they were testing out the mustaches in the first place as they were not males and would never use them on missions.
