A guy is trying to relax at home

A man is attempting to chill out at residence, however his spouse retains nagging him to mow the garden.

Lastly, in between nags he blurts out, “Reply simply this one query for me.”

She pauses momentarily, and he takes this chance to say, “You recognize, a Deer, a Cow, and a Horse, all eat grass.

However a Deer’s excretions are pellets, whereas a Cow makes flat pies, and a Horse makes clumps…why is that?”

His spouse says, “I don’t know.”

He replies, “Effectively then, how are you going to convey up the topic of the garden, when it’s apparent you don’t know sh*t?”
