None of the MI games have text parsers proper, meaning typey-typey ones.
Instead, the first couple games have a PnC command line, as it were. There's three sections... command words (like Push, Pull, Pick Up, Use, etc.) an inventory section, and the main "world" screen.
To make your actions, you click on a command word, then click on either inventory or on something in the world screen. Like, you might click on "Use", then a fish in your inventory, then a bucket on the world screen, to get "Use fish in bucket."
I personally found it to be a rather nice blend between the flexibility of a typey text parser, and the ease of PnC, and it's one of my favorite interfaces. Plus, there's one section of Secret of Monkey Island that makes utterly hilarious and creative use of the command line, and is one of my favorite adventure game scenes in general.
Peace & Luv, Liz
