While someone you know is incapacitated either drunk or just heavily sleeping take rubber cement and apply it to the entire front section of a bare chest and bring the arms up to the chest, hold firmly until the rubber cement dries.

When the unsuspecting victim awakes they will find themslves doing the T-Rex and just as pissed.

John was so drunk last night we T-Rex'd him to get a laugh, you shold have seen his hands flailing around when he woke up, he had no idea what had just happened.
