I didn't do that with jalapenos, but with jellyfish. When I was in college I worked a summer job for a guy doing some work on his property -- he lived off an inlet of the Chesapeake Bay -- and one day he came up to my coworker and me and asked us to stop what we were doing and get the jellyfish away from his dock.
When we were done, I instinctively reached my gloved hand up to wipe off my sweat, not realizing that a stray jellyfish tentacle remained on my glove.
Long red mark across my forehead for a few days. And it HURT.
