A bird who knocks before delivering its message !
Knock knock jokes
Someone who pointlessly knocks on the door.
To get to 10.
Because he crossed the line
Toucan
It was for 'tick or tweet' !
Neither one delivers on Sunday!
Two large plains.
By ski-mail.
By sea-mail.
A bird that talks in morse code !
Because the woodpecker would peck 'er !
