The Traveling Gnome

I have an unfortunate tendency to beat every game I get to 100% completion, or attempt to at least. While playing Half-Life 2: Episode 2 I was looking though their accomplishment list and found one that forces you to take a garden gnome through most of the game just to place it in a rocket ship. This is probably the most worthless / evil accomplishment in the history of games because you have to transport the gnome in a car that is in very poor condition, in which the gnome can VERY easily fly out. Which means that when driving you have to have more control than Jack Traven in Speed! Well, after I beat HL2:Ep2 the first time, I guess I will have to go back and get this done.
