I agree with RT. The stinky fish trick is hard to beat. Several years ago a buddy and I were fishing the slag pile when I turned around to see him using some of my spare clothes to clean his bait knife. When caught in the act he just had this big **** grin on his face. Later when he wasn't looking I dropped a plug cut herring in his tackle box and covered it with a few squid jigs. About 4 days later I get this call late at night with him yelling about some gelataneous slime in his tackle box. I found it hard to breath I was laughing so hard when he told me the smell had been getting progessively worse over the last few days and wouldn't go away even though he took the garbage out, threw away all the empties and cleaned the bathroom. Finally, he trailed the scent into his spare bedroom where his tackle was stored.
