Great man! Great to see this clip finally "immortalized"!
There are actually 2 other tickling scenes in this movie, though not as "clear".
One is they're looking to buy a house, and he chases her into a closet....you don't see them once they get into the closet, but the way she is defending herself, both when she goes into the closet and when she comes out (she comes running out, escaping) implies that he's tickling her.
Also, on their wedding night, he gets at the foot of the bed, and crawls under the covers, up towards her.....and as he's moving up towards her, she's twitching and giggling and squealing, again...implying that he's probably tickling her.
There may even be another one, but those are the 3 scenes I remember.
Thanks for making a clip!!!
