"By Any Means" - 9pm Sun BBC 1. It's really good, light enough to be amusing, but good enough plot & fast moving to keep interest.
"The Wrong Mans" - 8:30pm Tues BBC 2. Stupid humour at times but if you enjoyed Gavin and Stacey you'll probably enjoy this too. Sometimes makes me chuckle out loud in the dark when feeding baby overnight!
You could always use ITV player for "Fool Britannia" on a Friday night which again is quite humour-specific but makes me grin
