Pumpkin firebombs?

[Norther]

The UO Guide Halloween 2009 states that some pumpkins can be used as fire bombs.

Farmers are once again harvesting pumpkins this season. Pumpkins can be picked up from most any farm land. Some of them may be double-clicked and thrown as a fire bomb. Additionally, the named pumpkins may be used with the Cooking skill to prepare food items requiring pumpkin. The pumpkins can weigh anywhere from 3-25 stones and very rarely a Jack O' Lantern will spawn

Is that a mistake or has anybody found some that could be used as such.
The named ones I double clicked and nothing happens and the unnamed ones
that I try to harvest I just eat. Same if I double click the bought one .Thx

I heard only the black pumpkins from last year could be used as fire bombs. However I haven't one to try see if thas true.

I think that was left over from previous years. at least the last two years orange and black jackolanterns went up in flames if you double clicked. It waas great way to clear a pumpkin field.
