Happy Mudders Day Is The Better Choice

I sent one of my friends a Happy Birthday greeting this morning, then a second friend wished her a 'Happy Dirt-day'.

I responded to both friends: It's a good thing your dirt-day isn't in May on the second Sunday and it was raining, otherwise it would be Happy Mudders Day, but that's still bedder than what my spill chicker wanted, it changed 'mudders' to 'Happy Murders Day', a holiday which is usually not in the month of May.
