Jerry Lewis was certainly a flawed comedian and many of his films seen today are bound to fall flat in some spots while seeming overly dated in others. However, taking all his limitations into account, the truth is, he was a very funny personality. The fact is that he should be judged by his best work which is,
in some cases, positively hilarious. In any case, I remember him fondly and his typewriter skit always brings a smile to my face!
Incidentally, this gag appeared in his 1963 film WHO'S MINDING THE STORE?, which came out when Lewis' popularity was at its peak.
