Can't do

"What's wrong, sonny?" asked the old timer sympathetically, coming over to the little kid who was sitting on the curb, crying his heart out. "I'm crying 'cause I can't do what the big boys do!" So the old man sat down and wept too.

Grandma's Peanuts

A guy goes to visit his grandmother and he brings his friends with him. While he's talking to his grandmother, his friend starts eating the peanuts on the coffee table, and finishes them off. As they're leaving, his friend says to his grandmother, "Thanks for the peanuts." She says, "Yeah, since I lost my dentures I can only suck the chocolate off 'em."

Grandma's Strudel

An old man is lying on his deathbed with all his children, grandchildren and his older great-grandchildren all around, teary-eyed at the approaching finale of a very long and productive life. The old man in is a terminal coma, and the doctors have confirmed that the waiting will be over within the next twenty-four hours.
Suddenly, the old man opens his eyes and croaks, "I must be dreaming of heaven. I smell your grandmother's strudel."
"No, grandfather, you are not dreaming. Grandmother is baking strudel now."
"I know I will never have another taste of her delicious strudel after this one. Could you please go down and get me a sliver?" the old man begs with what is left of his final breath.
One of the grandchildren is immediately dispatched to honor the old man's last request. After a long time, he returns empty-handed. "Did you bring me one last piece of your grandmother's delicious strudel?" the old man plaintively queries.
"I'm very sorry, grandfather, she says you can't have any, it's for the funeral!"
