Thanks to the miniaturized batteries and tiny audio devices that are available today, many funny birthday cards can even include built_in speakers that announce hilarious quotes or sounds to the delight of the birthday card recipient. Although most of these types of cards come with their own pre_made recordings, some of these humor greeting cards can be ordered on_line and the card giver can include a private message to add a very personal touch to the funny birthday greeting card.
Humor birthday cards with unusually large shapes and sizes are also very effective ways to heighten a birthday party celebration. Just as how they can hold an enormous amount of content, the cards can also command an equally enormous amount of attention and detail. More importantly, the card's excess space and size will come in handy for hiding special knickknacks and novelty gags or a gift card without being too bulging or tearing the envelope.
