GTA IV PC Glitch?

[Psychospacecow]

With the fist selected as the current weapon, the player can pick up random objects off the streets such as a bricks and bottles. However, the player cannot switch weapons while an item is picked up. All items on the street that the player picks up do the same damage when thrown at someone. Objects which can be picked up and thrown will not disappear no matter how far away it is from the player. Using an example, if the player picks up an object from a rooftop and throws it down the from the balcony, the player will still find the object which he/she threw earlier on in its original condition on the ground when the player reaches street level.

Its stretching but find something to pick up.
