FUNNY?      Yes
STUPID?     Yes

This falls right in there with throwing stink bombs, pulling the fire alarms,  making false bomb threats, etc. etc. etc.
Only problem is:  these things used to be funny, now they're crimes, some are even felonies.
High School pranks just aren't what they used to be!   And we have our "wonderful government" to thank for this.
Probably the only reason they fed them at all is so they would make a bigger mess,  just glad that's what they had in mind.
And I too noticed they're not RIR, actually, they look like sex links.
