What I'm supposed to do with this Chainsaw?

Question

In the old Maniac Mansion Game for the commodore 64, you could find a Chainsaw in the kitchen.

I never found any use for it!

I always wondered what I'm supposed to do with it?

Is there anyone who could make it work? Maybe Bernard could "cook" some gas?

Answer 1

Of course some Lucasarts humour:

The game featured some notorious red herrings, such as a chainsaw for which there was no fuel, despite many wishful rumours to the contrary. In one of the in-jokes that are a hallmark of the LucasArts adventure games, the second SCUMM game, Zak McKracken and the Alien Mindbenders, contains some fuel "for chainsaws only", but no chainsaws.
