Big Bang Theory was unrelentingly hilarious.
And a reasonably well-disguised rom-com across its entire run.
I don't particularly like rom-coms (I couldn't get on with
Friends at all, or the various rom-com films), but I've watched all the episodes of
The Big Bang Theory at least twice (as it's continually being repeated on E4 here in the UK, often when I'm making a meal)... and the jokes and situations bear repeating.
There was a thread about the show on here and how it could be a bit cruel to one or other of the major characters at one time or another...
...but I was brought up on the gem that was
Steptoe and Son (both on the radio and the TV), where the whole point was there was at least one character being the "monster" in an episode. It varied from week to week as to which of the two main characters took on this role, but the situations they got into were both very funny and often profoundly tragic, as neither main character could escape** from the other... nor, deep down, really wanted to (other than briefly).
** - Producing comedies in which a character is trapped is very hard to do, and there are umpteen shows where it is done
very badly. I recall listening (though not for very long) to one where someone kept being interrupted by people ringing the doorbell. Why oh why did she not simply ignore them when she had something or other very important for her to do (which, never got done)? If it had been a comedy set in an office it would have made more sense, but the character always opened the door of her home and got involved (very unfunnily) with whomever had randomly washed up on her doorstep.
Another "comedy" simply had a family whose children had all returned home, often for no better reason than it drove the plot (badly) and everything flowed (unbelievably) from that. Basically, the show was full of "monsters" who thought about nothing but themselves, with one or two of the other characters being persuaded to give way over and over again for no good reason at all. (Of course, now that situation is more like reality -- in terms of people being forced back into the family home -- so, give or take the awful writing, that situation may work these days.)
