"manly" thank you cards?

The thing I don't get is why my husband and son are having such a cow of a few little flowers on a thank you card. All I'm asking is to have a manly thank you card- says the husband, LOL! Manly? What's this "manly" thing? Does that mean less flowers? Or is it no flowers? I made the cards in shades of blue with little flowers, but apparently they guys want it with NO flowers :-( I'm a flower lover, I'm surrounded by them how can I not put flowers on anything? So all I did was to hunt up a thank you stamp and use the same design that I did for the graduation cards and turned those into thank you cards. There- are those manly enough? Yes they were- now for me to move on to something else...Men!
