(Caution, it's a long one.)
This one happened after ice fishing. We had a guy follow us up ice fishing in Minocqua which is a 2 1/2 hour drive north from where we live. We didn't want him to come with us, but he invited himself. He repeated to use our ice drills cause he didn't have his. Then invited himself to stay in our motel rooms we booked, he paid, but it was tight then. Then he proceeds to tell us on the way to Big St. Germain about how we should fish and what to do. Anyhow he hardly catches a thing while the rest of us get some perch, northern, and I picked up my biggest walleye to date. After him b***hing all night, I told the guys he's gonna have a surprise in the morning. He goes to get some breakfast (doesn't even ask us, just goes cause he didn't wanna wait he tells us later), so I had my chance. He always takes a dump before we leave to fish. So I took a warm snickers I had in my pocked, smeared it on my hands, then grabbed a bunch of TP and wadded it up and pulled it apart so it looks like doody on it, and hung it all over the toilet seat. So he gets back from breakfast, runs to the bathroom cause he has to go, and sees the "doody TP" and freaks out and starts gagging. We bust out laughing and enjoyed out Revence.
