Wikipedia

To pass the time until he can start putting up the Xmas Decorations, Wilson is drafting a letter of complaint to Wikipedia. He takes exception to Tamanduas, of which he is one, being described by them as the 'Common or Lesser Anteater.'

'We are neither "common" nor "lesser", New Dad — and I shall tell them so in no uncertain terms!'

This is exactly like the time he complained to an on-line dictionary for claiming that Vermilingua, his family name, means 'Worm Tongue.' 

He'll get no satisfaction and just make himself cross…
