go all Indiana Jones on me

How someone refers to another person's forcefully admonishing him to donate one or more of his prized possessions to a historical-society collection ("That beLONGS in a muSEUM!"), rather than his selfishly either hoarding it in his own private collection or (even more horrifying) selling it for personal profit.

Antiques collector: I knew that the head of the local heritage-preservation lodge was a bit fanatical about collecting and displaying vintage images and artifacts from the area, but I never expected him to go all Indiana Jones on me when I showed him my collection of old coins and arrowheads that I'd found in the area here over the years.
