... really sucks. I finally realized that once a person reaches 80 years old, you can't tell them jokes any more.

A typical exchange between me and my mother:

me: What do call a fly with no wings?
her: ha ha ha ha ha!!!!
me: Mom... I haven't told the joke yet.. what are you laughing at??
her: Oh..ok, say it again.
me: What do call a fly with no wings?
her: What?
me: A walk
her: A wok?
me: No.. a walk... you know a walk, like walking along
her: oh.. sorry, what was it again?
me: What do call a fly with no wings?
her: What?
me: A walk.
her: Oh... a WALK. I thought you said WOK. You sound too American.
me: yeah ...but... oh never mind.
her: I don't get it.. it's a fly?
me: arghh...never mind!!
