Bug Verification Project
Find Mister Cuddles in the south hangar where the B-29 is being rebuilt (where Loyal and Jack are). Stand behind the tail of the B-29, then face north-north-east. Mister Cuddles is located amongst the green crates on the ground. With a Speech check of 60, you can lie and tell Lindsay that Mister Cuddles is dead. She will run away crying, resulting in a small amount of infamy (and bad Karma) with the Boomers.
