These are the Admiral Ackbar brand mouse traps created by Cullen Sweet. In case you've been living under a rock your entire life, Admiral Ackbar is famous for yelling, 'IT'S A TARP!' during the Battle of Endor. "Trap, not tarp." You know, one day I'm going to get around to actually watching those movies.
Thanks to Doctor Joe, who isn't actually allowed to practice medicine anymore since the incident.
