I wish I could get the answers to these the way Wofa does. When I look at them my mind goes blank!

Wofa got most of my last offering, but tsuwm and wwh were right with 3 Men in a Boat.

24 = HTT is 24 hours to Tulsa
12 on a J is 12 on a jury (bit weak really)

WW goes in for one-upmanship by saying “Here are some easy ones”. Huh! 32 O in Q, yes OK, but the rest? No way José.

A few more 'simple' ones here (as WW would say!)

3 C in the F
7 C of the R
12 S of the Z
4 C of the E
101 Ds
1814 WTaLTAWCJDtheMM
86400 S = 1440 M = 1 D
103 E in the PT
50 S in the U
