I've used beer before to get rid of slugs in the garden. That method does take patience and consistency though. I put jar lids on the ground and put beer in them in the morning. The next day there'd be a few dead slugs in the lid... something in the beer attracts them (like Pete said a few posts above, cheap dates), they crawl in and get bloated and die (not exactly like a cheap date, just sort of... I prefer it when dates don't bloat OR die). But each day you have to empty out the lids, then refill the with more beer. (And if it rains just start over). Took a week or two of that treatment for me, but it worked.
I've seen the salt trick that Noss told of too... they foam and shrivel. I did find that salt worked to get the slime off my hands. Just ordinary table salt... washed my hands "dry" in salt, then rinsed and used lava soap. For those of you with delicate skin, probably some lotion after that. (The salt plus lava soap really dries your skin).
OK, so it's not exactly like a party, but the good news was that it got me to open a beer every day for a week or two. :-)

p.s. I used cheap beer (didn't want to waste the good stuff... I suppose if we want to get off topic we could start a discussion about beer and which kinds work best for slugs as well as for cheap dates :-). I did wonder if I was accidentally ATTRACTING slugs to the area. But it worked out OK for me.
