What episode looney tunes ends w/ character trying to remember what he was looking for?

He forgets what he is looking for and says at one point “orangutan?” and then laughs at himself saying “no. no couldn’t be an orangutan”.
I think it ends with him sitting under a tree as night falls and he is still trying to figure out what he is looking for.
That is all I can remember of that episode and was wondering what other details anyone can fill in…

Hare-Less Wolf
A good one!

“Now why was I trying to catch a train?”

EXACTLY what I was looking for! Thanks for quick and accurate reply.

Are you sure that’s what you were looking for?

Heh. I love the bit at the 1:00 where Bugs is bouncing up and down like a three-year-old, eagerly asking what he’s hunting.

And that was a 24-second fuse on the grenade.
