Otay, this one's Scrambler's fault. He asked for it.
Back in my LEO days (in Kotzebue, AK)... one of the guys I worked with had "that brother-in-law". The one that had no place to live and mooched off his sister's good will. Jeff tells us this tale from one of his dealings with this BIL. Jeff's sitting on the couch, watching some tube, and his BIL looks at him and says: "I know when you're having sex with my sister." Jeff's like... "WTF??? And, what business is it of YOURS?!?!?!" Now, mind you, this BIL wasn't "straight"... he tells Jeff that he goes into the waste basket and drinks the condom afterwards. Yeah, that went over well. Jeff tells this tale to two of us before we drop him off at home after his shift.
Dean (the other cop hearing this tale) and I (although creeped out by this), have a hearty laugh about it with Jeff as we bid him goodnight.
At the end of our shift, we're about to pick up Jeff, since he's coming back on shift again. Dean swings by the grocery store and goes in. We pick up Jeff, and when he gets into the vehicle with us, Dean pulls out a condom (filled with doughnut glaze) and holds it up and oozes it into his mouth. Poor Jeff, just about lost it on the spot. A good laugh was then had by all.
True story.
