I pocket the poppers, cover the party hat with tinfoil from a nearby garbage can, wear the tinfoil hat, grab the gun (which may or may not be non-fake and actually a plastic gun like the ones in the third X-Men movie), and engage in some Solid Snake-style stealth stuff (minus the extended-length cutscenes, because I don't have the time for those) to find somewhere safer than a seedy motel.
