Henry finds out the meaning of best friend - but in the end, will his real character be revealed?


Henry finds a dog which calls Basher. They go and see what Margaret and Susan are doing. Henry tells Basher 'Girls' as Basher growls. Margaret asks if Lady Susan wants a custard cream. Susan says yes to Madam Margaret. Henry and Basher lick their tongue out to the picnic, while Margaret and Susan were having and showing a cake as well. Basher goes to get it. Henry tells him not to. Then Henry asks them a joke which Margaret hopes would be good. The joke was, 'What's got 4 legs, 4 eyes and smells of stinky cheese?'. Margaret and Susan don't know as Basher takes the picnic into Henry's garden. Henry says them. Margaret laughs fakely. Margaret and Susan turn around and realize that their picnic was gone. Margaret soon starts to scream.
