Step-by-step explanation:
The humor in the expression, 'I better than the cook,' can be found in the unexpected and comical response from the oiler and the correspondent when the cook asks what kind of pie they like best.
Instead of answering his question seriously, they respond with agitation and tell him not to talk about pie.
The humor lies in the contrast between the cook's innocent question about pie and the intense reaction it elicits from the other characters.
