Once I went to a museum and over heard someone speaking to an employee for information.
"These are lying clocks, they tell how many lies a person tells."
"oh cool"
"this is mother Teresa's clock, the clock hasn't moved because she never lied."
"Makes sense"
"This is Abraham Lincoln's clock. The hands only moved twice indicating he only lied twice."
"Where's Trump's clock"
"Oh, we're using it as a ceiling fan."
And then I burst out laughing 'cause it's so true.
Unknowen
Best one i have ever hear!
