Should I ask my husband to shave his beard because everyone thinks it looks funny?
Does his beard look funny to you or to others?
It does look kind of silly.
You should just let your husband decide on that. It's not really appropriate to judge someone, especially making them do something they don't want to. You are technically bullying your husband and you might cause him to have low self-esteem by laughing at his looks.
He's been holding on it for a while and I want that thing off.
If he is holding on to it, it is probably because it means a lot to him. I bet his beard makes him feel like more of a man, and that helps give him more self-esteem. I think you shouldn't make him shave because it really should be what he wants since it is his beard.
