Honey, We've Been Swallowed By Grandpa

S1 E1: Nick feigns illness to avoid going with his grandfather, who leaves but not before inadvertently swallowing his mini-relatives -- van and all. Nick interprets Wayne's help message in the newspaper and, realizing what has happened, rushes to his family's aid. It's a race against the clock as the tiny Szalinskis travel on a "fantastic voyage" through Grandpa's body, seeking a way out before the shrinking effect wears off in three hours.
