I almost forgot about the Guy playing a Ranger at the convention I went to back in 2nd ed days.
He combined a Decantur of Endless Water, some Soveriegn Glue and hid in a Fire Giant's Outhouse.
When the Giant came in, he Inserted the Decantur in the, umm, tunnel, the Giant, rather hastily, was planing on becoming Exit Only (Roast Halfling must have set off his Irritable Bowel Syndrome), Then, as the Giant was thinking "Hey, I've had my Proctology Exam for this year." The Ranger then activated the 'Geyser' Ability of Said Decantur, which was firmly lodged within the Giant's derriere due to the Soveregin Glue.
Thus the Giant Recived an Enema, if the NY Fire Department did house calls.
In the end (no pun), we found out several things.
1. Fire Giants' Colons are capable of significant Expansion.
2. While a 22 Strength is Insufficent to pull apart 2 surfaces joined by Sovereign Glue, It is Sufficent to rip the Skin off a Fire Giant's Booty (both Inside & out).
3. Fire Giant's Walk Funny when afflicted by Severe Hemorrhoids.
4. That which Goes Up. Must Come Back Out. And Out. And Out. And Out. And Out.
5. After causing a Fire Giant to have have several hours of explosive diarrhea, you should really, really remember to leave your hiding place in the outhouse before said Giant settles down with a copy of War and Peace.
6. Nothing removes Fire Giant Fecal Stains From Elven Chain.
