Three carpets in a hallway, each short enough to jump over.
The first covers a simple pit trap.
The second covers a pit trap with an invisable wall over the carpet. Try to jump it, hit the wall and bam, in the pit.
The third trap is as the second, with convenient hand-holds in the sides of the walls. The bottom of the pit is a pressure plate, that causes the pit to seal, with the party inside.
I recall a rather devious trap (could be used in any game really).
You have a single, somewhat large room filled with bones, corpses, etc. Line the walls with whatever deadly looking devices you like. There is a single entrance/exit in the room. On the far wall from the door is a clock with a button under it.
When the adventurers enter the room, the door closes and locks behind them, and the clock begins to tick down. Should one of the adventurers hit the button, the clock will reset and count down from the beginning.
Most likely, one of them will hit the button before the clock finishes its first count down, and the rest of the party will search the room while one of them keeps mashing the button. There is no way to open the door, and the room contains no other way out.
Should the clock finish its count down, the door will slid open.

If I have thieves checking every door obsessively for traps, I put spiked pits just behind the door. They check the door for traps, find none, open it, step through and fall into the pit.

One trap I threw at a party...
An anti-rogue device. It is clearly a trap... but there is no mechanism to activate it... except for attempting to disarm the trap. So I guess its not really a trap in the "I can disable it" kind of sense... more in the if you try and disable it it goes off. I usually attach it to an explosive charge... and even then only when the party needs a kick in the pants.

Now for a bit of fun rather than reveal my trap why don't a few people post what they or their party would do here and then I'll post a desription of the trap and what happened when my party encountered it.
