Two funny ones off the top of my head.
During his Columbus tenure, Mike Sillinger once got a breakaway despite not having a stick. He lost it in the neutral zone, then got stranded on a dump-in. The defenseman didn't realize that Sillinger was without a stick and hit him with a perfect pass in the skates. Of course, since the rule says that you can't kick the puck directly off the goalie and into the net, he skated in and then kicked the puck into the corner.
In his first career win, which was a shootout (8-7 or 7-6 in OT), Darren Madeley of Ottawa stoned Teemu Selanne in the last 0:10 of regulation. He came in in relief of...I think it was Craig Billington to start the third period. Madeley didn't allow a goal, and Ottawa won it in overtime.
The funny thing was that Madeley gave an interview a couple years later and was asked about it. He said something like "I'd spent the last year in the AHL and didn't have a book on Selanne, and the new season had just started so I still didn't. Also, I didn't know it was him on the breakaway, because if I did, I'd probably have been crying in the fetal position in the corner instead of trying to stop him."
