your what?

Through my uni account, I often get emails from people who have lost iphones/USB's/etc. However, just then I read this in an email with subject "Missing Black Tube":

If anyone come across my bazooka, anywhere in the building, please contact
me on my mobile, XXXXXXXXX or by replying to this email.

I will assume that a bazooka can be many other things other than what I had in mind....
